SONIC CORP.

PART I

Item 1. Business

General

Sonic Corp.
operates and franchises the largest chain of drive-in restaurants (Sonic Drive-Ins) in the United States. References to Sonic Corp., the Company, we, us, and our in this Form
10-K are references to Sonic Corp. and its subsidiaries.

The Sonic Drive-In restaurant chain began in the early 1950s.
Sonic Corp. was incorporated in the State of Delaware in 1990 in connection with its 1991 public offering of common stock. Our principal executive offices are located at 300 Johnny Bench Drive, Oklahoma City, Oklahoma 73104. Our telephone number is
(405) 225-5000.

The Sonic Brand

At a standard Sonic Drive-In restaurant, a customer drives into one of 20 to 36 covered drive-in spaces, orders through an intercom speaker system, and has the food delivered by a carhop. Most Sonic
Drive-Ins also include a drive-thru lane and patio seating.

Sonic Drive-Ins feature Sonic signature
items, such as specialty drinks including cherry limeades and slushes, frozen desserts, made-to-order sandwiches and hamburgers, footlong quarter pound chili cheese coneys, hand-battered onion rings, tots, salads, and wraps. Sonic Drive-Ins also
offer breakfast items that include sausage or bacon with egg and cheese Breakfast Toaster®, or CroisSONIC® breakfast sandwiches, and breakfast burritos. Sonic Drive-Ins serve the full menu all day.

Business Strategy

Our
objective is to maintain our position as or to become a leading restaurant operator in all of our markets. We have developed and implemented a strategy designed to build the Sonic brand and to maintain high levels of customer satisfaction and repeat
business. The key elements of that strategy are: (1) a unique drive-in concept focusing on a distinctive menu of quality made-to-order food products including several signature items; (2) a commitment to customer service featuring the
quick delivery of food by carhops; (3) the expansion of Sonic Drive-Ins within the continental United States; and (4) a commitment to strong franchisee relationships.

Expansion

During fiscal year 2010, we opened 85 Sonic Drive-Ins, which consisted of five Company-owned Drive-Ins and 80 Franchise Drive-Ins. Expansion plans for fiscal year 2011 involve the opening of multiple
Sonic Drive-Ins under area development agreements, as well as single-store development by long-standing franchisees. We believe that our existing as well as newly opened markets offer significant growth opportunities for both Company-owned Drive-In
and Franchise Drive-In expansion over the long term. In the near term, unit growth will be impacted by the recent decline in sales and profits.

Restaurant Design and Construction

The typical Sonic Drive-In consists of a kitchen housed in a one-story building flanked by canopy-covered rows of 20 to 36
parking spaces, with each space having its own payment terminal, intercom speaker system and menu board. In addition, most Sonic Drive-Ins incorporate a drive-thru service and patio seating area.

Marketing

We have
designed our marketing program to differentiate Sonic Drive-Ins from our competitors by emphasizing high quality distinctive made-to-order menu items and personalized service featuring skating carhops. The marketing plan includes promotions for use
throughout the Sonic chain. We support those promotions with television, radio, interactive media, point-of-sale materials, and other media as appropriate. Those promotions generally center on products which highlight new product introductions for a
limited time and signature menu items.

Each year Sonic develops a marketing plan with the involvement of the Sonic Franchise
Advisory Council. (Information concerning the Sonic Franchise Advisory Council is set forth on page 5 under Franchise Program -Franchise Advisory Council.) Funding for our marketing plan is comprised of the System Marketing Fund, the Sonic
Brand Fund and local advertising expenditures. The System Marketing Fund focuses on purchasing advertising on national cable and broadcast networks and other national media, sponsorship and brand enhancement opportunities. In addition, a portion of
the System Marketing Fund is re-allocated to local markets to optimize impressions in a drive-in trade area. The Sonic Brand Fund is our national media production fund. Franchisees are also required to spend additional amounts on local advertising,
typically through participation in the local advertising cooperative. Our franchise agreements require advertising contributions by franchisees of up to 5.9% of gross sales to these marketing funds and local advertising cooperatives.

The total amount spent on media (principally television) was approximately $167 million for fiscal year 2010, and we expect media
expenditures to be approximately $170 million for fiscal 2011.

Purchasing

We negotiate with suppliers for our primary food products and packaging supplies to ensure adequate quantities of food and supplies and to
obtain competitive prices. We seek competitive bids from suppliers on many of our food products. We approve suppliers of those products and require them to adhere to our established product and food safety specifications. Suppliers manufacture
several key products for Sonic under private label and sell them to authorized distributors for resale to Sonic Drive-Ins. We require all Sonic Drive-Ins to purchase from approved distribution centers.

Food Safety and Quality Assurance

To ensure the consistent delivery of safe, high-quality food, we created a food safety and quality assurance program. Sonics food safety program promotes the quality and safety of all products and
procedures utilized by all Sonic Drive-Ins, and provides certain requirements that must be adhered to by all suppliers, distributors, and Sonic Drive-Ins. We also have a comprehensive, restaurant-based food safety program called Sonic Safe. Sonic
Safe is a risk-based system that utilizes Hazard Analysis & Critical Control Points (HACCP) principles for managing food safety and quality. Our food safety program includes employee training, supplier product inspections and testing,
unannounced drive-in food safety auditing by independent third-parties, and other detailed components that monitor the safety and quality of Sonics products and procedures at every stage of the food preparation and the production cycle. All
Sonic Drive-In employees are required to be trained in food safety in their first stage of training, utilizing an internal training program, referred to as the STAR Training Program. This program includes specific training on food safety information
and requirements for every station in the drive-in. We also require our drive-in managers and assistant managers to pass and maintain the ServSafe® certification. ServSafe® is the most recognized food safety training certification in the
restaurant industry.

Company Operations

Restaurant Personnel. A typical Company-owned Drive-In is operated by a manager, two to four assistant managers, and approximately
25 hourly employees, many of whom work part-time. The manager has responsibility for the day-to-day operations of the Company-owned Drive-In.

Ownership Structure. Company-owned Drive-Ins are drive-in operations in which SRI, as the Companys operating subsidiary, owns a controlling ownership interest. Effective April 1,
2010, the Company introduced a new compensation program as an alternative to the prior form of ownership to improve manager and supervisor retention. While managers and supervisors do not own an interest in the drive-in under the new compensation
program, the program provides managers and supervisors a larger portion of guaranteed compensation, but retains a significant incentive component based on drive-in level performance. With this change, 95% of Company-owned Drive-Ins now operate under
the new compensation structure. Historically, Company-owned Drive-Ins operated as individual limited liability companies or general partnerships in which the manager and the supervisor for the respective drive-in owned a noncontrolling interest.
Under this form of ownership, managers and supervisors shared in the cash flow for their Company-owned Drive-In, but were also responsible for their share of any losses incurred by the drive-in.

Company-owned Drive-In Data. The following table provides certain financial information relating to Company-owned Drive-Ins and
the number of Company-owned Drive-Ins opened and closed during the past five fiscal years.

Franchise Program

General. As of August 31, 2010, we had 3,117 Franchise Drive-Ins in operation. A large number of successful multi-unit
franchisee groups have developed during the Sonic systems 57 years of operation. Those franchisees continue to develop new Franchise Drive-Ins in their franchise territories either through area development agreements or single-site
development. Our franchisees opened 80 Franchise Drive-Ins during fiscal year 2010. We consider our franchisees a vital part of our continued growth and believe our relationship with our franchisees is good.

Franchise Agreements. For traditional drive-ins, the current franchise agreement provides for an initial franchise fee of $45,000
per drive-in, a royalty fee of up to 5% of gross sales on a graduated percentage basis, advertising fees of up to 5.9% of gross sales, and a 20-year term. For fiscal year 2010, Sonics average royalty rate was equal to 3.82%.

Area Development Agreements. We use area development agreements to facilitate the planned expansion of the Sonic Drive-In
restaurant chain through multiple unit development. While many existing franchisees continue to expand on a single drive-in basis, approximately 83% of the new Franchise Drive-Ins opened during fiscal year 2010 occurred as a result of then-existing
area development agreements. Each area development agreement gives a developer the exclusive right to construct, own, and operate Sonic Drive-Ins within a defined area. In exchange, each developer agrees to open a minimum number of Sonic Drive-Ins
in the area within a prescribed time period.

We offer development agreements for construction of one or more new Sonic
Drive-Ins over a defined period of time and in a defined geographic area. Franchisees who enter into development agreements are required to pay a fee, a portion of which is credited against franchise fees due when Sonic Drive-Ins are opened in the
future. Franchisees may forfeit such fees and lose their rights to future development if they do not maintain the required schedule of openings.

Franchise Drive-In
Development. We assist each franchisee in selecting sites and developing Sonic Drive-Ins. Each franchisee has responsibility for selecting the franchisees drive-in location but must obtain our approval of each Sonic Drive-In design and
each location based on accessibility and visibility of the site and targeted demographic factors, including population density, income, age, and traffic. We provide our franchisees with the physical specifications for the typical Sonic Drive-In.

From time to time, at our discretion, the Company offers incentives to franchisees to increase the development of Sonic
Drive-Ins in certain markets. These incentives typically offer reduced or waived franchise fees and/or royalty fees upon certain conditions.

Franchisee Financing. Other than the agreements described below, we do not generally provide financing to franchisees or guarantee loans to franchisees made by third parties.

We had an agreement with GE Capital Franchise Finance Corporation (GEC) pursuant to which GEC made loans to existing Sonic
franchisees who met certain underwriting criteria set by GEC. Under the terms of the agreement with GEC, Sonic provided a guaranty of 10% of the outstanding balance of a loan from GEC to the Sonic franchisee. The portions of loans made by GEC to
Sonic franchisees that are guaranteed by the Company total approximately $946,000 as of August 31, 2010. We ceased guaranteeing new loans made under the program during fiscal year 2002. In April 2010, we paid approximately $166,000 to GEC
pursuant to our guaranty for one franchisee.

We have an agreement with First Franchise Capital Corporation (FFCC)
pursuant to which FFCC has agreed to make loans to existing Sonic franchisees who meet certain underwriting criteria set by FFCC to finance the equipment and improvements for our retrofit program in which significant trade dress modifications are
being made to Sonic Drive-Ins. Under the terms of the agreement with FFCC, we will provide a guaranty to FFCC of the greater of (i) 5% of the outstanding balance of a loan from FFCC to the Sonic franchisee or (ii) $250,000, provided
that in no event will our maximum liability to FFCC exceed $3.75 million in the aggregate. As of August 31, 2010, the total amount guaranteed under the FFCC agreement was approximately $563,000.

Franchise Advisory Council. Our Franchise Advisory Council provides advice, counsel, and input to Sonic on important issues
impacting the business, such as marketing and promotions, operations, purchasing, building design, human resources, technology, and new products. The Franchise Advisory Council currently consists of 22 members selected by Sonic. We have seven
executive committee members who are selected at large, 13 regional members representing four defined regions of the country, and two at large members representing new franchisees and smaller operators. We have four Franchise Advisory Council task
groups comprised of approximately 65 members who serve three-year terms and lend support on individual key priorities.

Franchise Drive-In Data. The following table provides certain financial information relating to Franchise Drive-Ins and the number
of Franchise Drive-Ins opened, purchased from or sold to Sonic, and closed during Sonics last five fiscal years.

Competition

We compete in the restaurant industry, a highly competitive industry in terms of price, service, location, and food quality. The
restaurant industry is often affected by changes in consumer trends, economic conditions, demographics, traffic patterns, and concerns about the nutritional content of quick-service foods. We compete on the basis of distinctive food and service with
signature food items and skating carhops and the method of food preparation (made-to-order). The quality of service, featuring Sonic carhops, constitutes one of our primary marketable points of difference from the competition. There are many
well-established competitors with substantially greater financial and other resources. These competitors include a large number of national, regional, and local food services, including quick-service restaurants and casual dining restaurants. A
significant change in pricing or other marketing strategies by one or more of those competitors could have an adverse impact on Sonics sales, earnings, and growth. In selling franchises, we also compete with many franchisors of quick-service
and other restaurants and other business opportunities.

Seasonality

Our results during Sonics second fiscal quarter (the months of December, January and February) generally are lower than other
quarters because of the lower temperatures in the locations of a number of Company-owned Drive-Ins and Franchise Drive-Ins, which tends to reduce customer visits to our drive-ins.

Employees

As of August 31, 2010, we had 340 full-time corporate
employees and approximately 12,400 full-time and part-time restaurant employees. None of our employees are subject to a collective bargaining agreement. We believe that we have good labor relations with our employees.

Intellectual Property

Sonic owns or is licensed to use valuable intellectual property including trademarks, service marks, patents, copyrights, trade secrets
and other proprietary information, including the Sonic logo and trademark, which are of material importance to our business. Depending on the jurisdiction, trademarks and service marks generally are valid as long as they are used and/or
registered. Patents, copyrights and licenses are of varying durations.

Customers

Our business is not dependent upon either a single customer or small group of customers.

Government Contracts

No
portion of our business is subject to renegotiation of profits or termination of contracts or subcontracts at the election of the U.S. government.

Environmental Matters

We are not aware of any federal, state or local
environmental laws or regulations that will materially affect our earnings or competitive position or result in material capital expenditures. However, we cannot predict the effect on operations of possible future environmental legislation or
regulations. During fiscal year 2010, there were no material capital expenditures for environmental control facilities, and no such material expenditures are anticipated.

Item 1A. Risk Factors

This Annual Report on Form 10-K includes forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. A forward-looking statement is neither a prediction nor
a guarantee of future events or circumstances, and those future events or circumstances may not occur. Investors should not place undue reliance on the forward-looking statements, which speak only as of the date of this report. These forward-looking
statements are all based on currently available operating, financial and competitive information and are subject to various risks and uncertainties. Our actual future results and trends may differ materially depending on a variety of factors
including, but not limited to, the risks and uncertainties discussed below. Accordingly, such forward-looking statements do not purport to be predictions of future events or circumstances and may not be realized. For these reasons, you should not
place undue reliance on forward-looking statements. We undertake no obligation to publicly update or revise them, except as may be required by law.

Events reported in the media, such as incidents involving food-borne illnesses or food tampering, whether or not accurate, can cause damage to our reputation and rapidly affect sales and profitability.

Reports, whether true or not, of food-borne illnesses, such as e-coli, avian flu, bovine spongiform encephalopathy
(commonly known as mad cow disease), hepatitis A or salmonella, and injuries caused by food tampering have in the past severely injured the reputations of participants in the restaurant industry and could in the future affect us. The potential for
terrorism of our nations food supply also exists and, if such an event occurs, it could have a negative impact on our brands reputation and could severely hurt sales, revenues, and profits.

Our brands reputation is an important asset to the business; as a result, anything that damages our brands reputation could
immediately and severely hurt sales, revenues, and profits. If customers become ill from food-borne illnesses or food tampering, we could also be forced to temporarily close some, or all, Sonic Drive-Ins. In addition, instances of food-borne
illnesses or food tampering occurring at the restaurants of competitors could, by resulting in negative publicity about the restaurant industry, adversely affect our sales on a local, regional, or national basis. A decrease in customer traffic as a
result of these health concerns or negative publicity, or as a result of a temporary closure of any Sonic Drive-Ins, could materially harm our brand, sales, and profitability.

The restaurant industry is highly competitive, and that competition could lower our revenues, margins, and market share.

The restaurant industry is intensely competitive with respect to price, service, location, personnel, dietary trends, including nutritional content of quick-service foods, and quality of food, and is
often affected by changes in consumer tastes and preferences, economic conditions, population, and traffic patterns. We compete with international, regional and local restaurants, some of which operate more restaurants and have greater financial
resources. We compete primarily through the quality, price, variety and value of food products offered and our distinctive service experience. Other key competitive factors include the number and location of restaurants, speed of service,
attractiveness of facilities, effectiveness of advertising and marketing programs, and new product development by us and our competitors. Some of our competitors have substantially larger marketing budgets, which may provide them with a competitive
advantage. In addition, our system competes within the quick-service restaurant industry not only for customers but also for management and hourly employees, suitable real estate sites, and qualified franchisees.

Changing dietary preferences may cause consumers to avoid our products in favor of alternative foods.

The restaurant industry is affected by consumer preferences and perceptions. Although we monitor these changing preferences and strive to
adapt to meet changing consumer needs, growth of our brand and, ultimately, system-wide sales depend on the sustained demand for our products. If dietary preferences and perceptions cause consumers to avoid certain products offered by Sonic
Drive-Ins in favor of different foods, demand for our products may be reduced, and our business could be harmed.

Our earnings and business
growth strategy depends in large part on the success of our franchisees, who exercise independent control of their businesses.

We have significantly increased the percentage of restaurants owned and operated by our franchisees. A portion of our earnings comes from royalties, rents and other amounts paid by our franchisees.
Franchisees are independent contractors, and their employees are not our employees. We provide training and support to, and monitor the operations of, our franchisees, but the quality of their drive-in operations may be diminished by any number of
factors beyond our control. Franchisees may not successfully operate drive-ins in a manner consistent with our high standards and requirements, and franchisees may not hire and train qualified managers and other restaurant personnel. Any operational
shortcoming of a Franchise Drive-In is likely to be attributed by consumers to the entire Sonic brand, thus damaging our reputation and potentially affecting revenues and profitability.

Changes in economic, market and
other conditions could adversely affect Sonic and its franchisees, and thereby Sonics operating results.

The
quick-service restaurant industry is affected by changes in economic conditions, consumer tastes and preferences and spending patterns, demographic trends, consumer perceptions of food safety, weather, traffic patterns, the type, number and location
of competing restaurants, and the effects of war or terrorist activities and any governmental responses thereto. Factors such as interest rates, inflation, gasoline prices, food costs, labor and benefit costs, legal claims, and the availability of
management and hourly employees also affect restaurant operations and administrative expenses. Economic conditions, including interest rates and other government policies impacting land and construction costs and the cost and availability of
borrowed funds, affect our ability and our franchisees ability to finance new restaurant development, improvements and additions to existing restaurants, and the acquisition of restaurants from, and sale of restaurants to, franchisees.
Inflation can cause increased food, labor and benefits costs and can increase our operating expenses. As operating expenses increase, we recover increased costs by increasing menu prices, to the extent permitted by competition and the consumer
environment, or by implementing alternative products or cost reduction procedures. We cannot ensure, however, that we will be able to recover increases in operating expenses in this manner.

Our financial results may fluctuate depending on various factors, many of which are beyond our control.

Our sales and operating results can vary from quarter to quarter and year to year depending on various factors, many of which are beyond our control. Certain events and factors may directly and
immediately decrease demand for our products. If customer demand decreases rapidly, our results of operations would also decline precipitously. These events and factors include:



| |  |  | variations in the timing and volume of Sonic Drive-Ins sales;
| | - |  | --------------------------------------------------------------



| |  |  | sales promotions by Sonic and its competitors;
| | - |  | ----------------------------------------------



| |  |  | changes in average same-store sales and customer visits;
| | - |  | --------------------------------------------------------



| |  |  | the inability to purchase sufficient levels of media;
| | - |  | -----------------------------------------------------



| |  |  | variations in the price, availability and shipping costs of supplies such as food products;
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | seasonal effects on demand for Sonics products;
| | - |  | ------------------------------------------------



| |  |  | unexpected slowdowns in new drive-in development efforts;
| | - |  | ---------------------------------------------------------



| |  |  | changes in competitive and economic conditions generally including increases in energy costs;
| | - |  | ---------------------------------------------------------------------------------------------



| |  |  | changes in the cost or availability of ingredients or labor;
| | - |  | ------------------------------------------------------------



| |  |  | unreliable or inefficient drive-in technology, including point-of-sale and payment systems;
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | weather and other acts of God; and
| | - |  | ----------------------------------



| |  |  | changes in the number of franchise agreement renewals.
| | - |  | ------------------------------------------------------

Our profitability may be adversely affected by increases in energy costs.

Our success depends in part on our ability to absorb increases in energy costs. If energy costs increase dramatically, they could have an
adverse effect on our profitability.

Shortages or interruptions in the supply or delivery of perishable food products or rapid price
increases could adversely affect our operating results.

We are dependent on frequent deliveries of perishable food
products that meet certain specifications. Shortages or interruptions in the supply of perishable food products may be caused by unanticipated demand, problems in production or distribution, acts of terrorism, financial or other difficulties of
suppliers, disease or food-borne illnesses, inclement weather or other conditions. We purchase large quantities of food and supplies, which can be subject to significant price fluctuations due to seasonal shifts, climate conditions, industry demand,
energy costs, changes in international commodity markets and other factors. These shortages or rapid price increases could adversely affect the availability, quality and cost of ingredients, which would likely lower revenues and reduce our
profitability.

Failure to successfully implement our growth strategy could reduce, or reduce the growth of, our revenue and net income.

We plan to increase the number of Sonic Drive-Ins, but may not be able to achieve our growth objectives, and any new
drive-ins may not be profitable. The opening and success of drive-ins depend on various factors, including:

If we are unable to open as many new drive-ins as planned, if the drive-ins are less profitable than anticipated or if we are otherwise unable to successfully implement our growth strategy, revenue and
profitability may grow more slowly or even decrease.

Our outstanding and future leverage could have an effect on our operations.

On December 20, 2006, the Company closed on a securitized financing facility comprised of a $600 million fixed rate
term loan and a $200 million variable rate revolving credit facility. As of August 31, 2010, we had $404 million in outstanding debt under the fixed rate notes at an interest rate of 5.7% and $187.3 million outstanding under the variable rate
notes at an interest rate of 1.4%.

Our increased leverage could have the following consequences:



| |  |  | We may be more vulnerable in the event of deterioration in our business, in the restaurant industry or in the economy generally. In addition, we may be
limited in our flexibility in planning for or reacting to changes in our business and the industry in which we operate.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We may be required to dedicate a substantial portion of our cash flow to the payment of principal and interest on our indebtedness, which could reduce
the amount of funds available for operations or development of new Company-owned Drive-Ins and thus place us at a competitive disadvantage as compared with competitors that are less leveraged.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | From time to time, we may engage in various capital markets, bank credit and other financing activities to meet our cash requirements. We may have
difficulty obtaining additional financing at economically acceptable interest rates.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Our existing and future debt obligations may contain certain negative covenants including limitations on liens, consolidations and mergers,
indebtedness, capital expenditures, asset dispositions, sale-leaseback transactions, stock repurchases and transactions with affiliates, which may reduce our flexibility in responding to changing business and economic conditions.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Our debt obligations are subject to customary rapid amortization events and events of default. Although management does not anticipate an event of
default or any other event of noncompliance with the provisions of the notes, if such an event occurred, the unpaid amounts outstanding could become immediately due and payable.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | On March 24, 2010, the Office of the Commissioner of Insurance of the State of Wisconsin (OCI) commenced rehabilitation proceedings
with respect to a segregated account of certain insurance policies held by Ambac Assurance Corporation (Ambac), the third-party insurance company that provides credit enhancements in the form of financial guaranties of our fixed and
variable rate note payments (the Segregated Account). Our insurance policy is not included in the Segregated Account and is not affected by the rehabilitation proceedings. Apart from its actions with regard to the Segregated Account, the
OCI continues to maintain oversight of Ambac. No delinquency, rehabilitation or similar proceeding involving our insurance policy is currently pending. If the insurance company were to become the subject of insolvency or similar proceedings, our
lenders would not be required to fund additional advances on our variable rate notes. In addition, an event of default would occur if: (i) the insurance company were to become the subject of insolvency or similar proceedings and (ii) the
insurance policy were not continued or sold to a third party (who would assume the insurance companys obligations under the policy), but instead were terminated or canceled as a result of those proceedings. In an event of default, all unpaid
amounts under the fixed and variable rate notes could become immediately due and payable only at the direction or consent of holders with a majority of the outstanding principal. Such acceleration of our debt could have a material adverse effect on
our liquidity if we were unable to negotiate mutually acceptable new terms with our lenders or if alternate funding were not available to us.

Sonic Drive-Ins are subject to
health, employment, environmental and other government regulations, and failure to comply with existing or future government regulations could expose us to litigation, damage to our reputation and lower profits.

Sonic and its franchisees are subject to various federal, state and local laws affecting their businesses. The successful development and
operation of restaurants depends to a significant extent on the selection and acquisition of suitable sites, which are subject to zoning, land use (including the placement of drive-thru windows), environmental (including litter), traffic and other
regulations. More stringent requirements of local and state governmental bodies with respect to zoning, land use and environmental factors could delay, prevent or make cost prohibitive the continuing operations of an existing restaurant or the
development of new restaurants in particular locations. Restaurant operations are also subject to licensing and regulation by state and local departments relating to health, food preparation, sanitation and safety standards, federal and state labor
and immigration laws (including applicable minimum wage requirements, overtime, working and safety conditions and work authorization requirements), federal and state laws prohibiting discrimination and other laws regulating the design and operation
of facilities, such as the Americans with Disabilities Act. If we fail to comply with any of these laws, we may be subject to governmental action or litigation, and our reputation could be accordingly harmed. Injury to our reputation would, in turn,
likely reduce revenues and profits.

In recent years, there has been an increased legislative, regulatory and consumer focus
on nutrition and advertising practices in the food industry, particularly among restaurants. As a result, we will become subject to regulatory initiatives in the area of nutritional content, disclosure or advertising, such as requirements to provide
information about the nutritional content of our food products, which could increase expenses. The operation of our franchise system is also subject to franchise laws and regulations enacted by a number of states and rules promulgated by the U.S.
Federal Trade Commission. Any future legislation regulating franchise relationships may negatively affect our operations, particularly our relationship with our franchisees. Failure to comply with new or existing franchise laws and regulations in
any jurisdiction or to obtain required government approvals could result in a ban or temporary suspension on future franchise sales. Changes in applicable accounting rules imposed by governmental regulators or private governing bodies could also
affect our reported results of operations.

We are subject to the Fair Labor Standards Act, which governs such matters as
minimum wage, overtime and other working conditions, along with the Americans with Disabilities Act, various family leave mandates and a variety of other laws enacted, or rules and regulations promulgated, by federal, state and local governmental
authorities that govern these and other employment matters. We have experienced and expect further increases in payroll expenses as a result of government-mandated increases in the minimum wage, and although such increases are not expected to be
material, there may be material increases in the future. Enactment and enforcement of various federal, state and local laws, rules and regulations on immigration and labor organizations may adversely impact the availability and costs of labor for
our restaurants in a particular area or across the United States. In addition, our vendors may be affected by higher minimum wage standards or availability of labor, which may increase the price of goods and services they supply to us.

We are reviewing the health care reform law enacted by Congress in March of 2010. As part of that review, we will evaluate the
potential impacts of this new law on our business, and accommodate various parts of the law as they take effect. There are no assurances that a combination of cost management and price increases can accommodate all of the costs associated with
compliance.

Litigation from customers, franchisees, employees and others could harm our reputation and impact operating results.

Claims of illness or injury relating to food content, food quality or food handling are common in the quick-service
restaurant industry. In addition, class action lawsuits have been filed, and may continue to be filed, against various quick-service restaurants alleging, among other things, that quick-service restaurants have failed to disclose the health risks
associated with foods we serve and that quick-service restaurants marketing practices have encouraged obesity and other health issues. In addition to decreasing our sales and profitability and diverting management resources, adverse publicity
or a substantial judgment against us could negatively impact our reputation, hindering the ability to attract and retain qualified franchisees and grow the business.

Further, we may be
subject to employee, franchisee and other claims in the future based on, among other things, discrimination, harassment, wrongful termination and wage, rest break and meal break issues, including those relating to overtime compensation.

We may not be able to adequately protect our intellectual property, which could decrease the value of our brand and products.

The success of our business depends on the continued ability to use existing trademarks, service marks and other components of our brand
in order to increase brand awareness and further develop branded products. All of the steps we have taken to protect our intellectual property may not be adequate.

Our reputation and business could be materially harmed as a result of data breaches.

Unauthorized intrusion into portions of our computer systems or those of our franchisees that process and store information related to customer transactions may result in the theft of customer data. We
rely on proprietary and commercially available systems, software, tools and monitoring to provide security for processing, transmission and storage of confidential customer information, such as payment card and personal information. Further, the
systems currently used for transmission and approval of payment card transactions, and the technology utilized in payment cards themselves, all of which can put payment card data at risk, are determined and legally mandated by payment card industry
standards, not by us. Improper activities by third-parties, advances in computer and software capabilities and encryption technology, new tools and discoveries and other events or developments may facilitate or result in a compromise or breach of
our or our franchisees computer systems. Any such compromises or breaches could cause interruptions in our operations and damage to our reputation, subject us to costs and liabilities and hurt sales, revenues and profits.

Disruptions in the financial markets may adversely impact the availability and cost of credit and consumer spending patterns.

The disruptions to the financial markets and continuing economic downturn have adversely impacted the availability of credit already
arranged and the availability and cost of credit in the future. The disruptions in the financial markets also had an adverse effect on the economy, which has negatively impacted consumer spending patterns. There can be no assurance that various
governmental responses to the disruptions in the financial markets will restore consumer confidence, stabilize the markets or increase liquidity or the availability of credit.

Ownership and leasing of significant amounts of real estate exposes us to possible liabilities and losses.

We own or lease the land and building for all Company-owned Drive-Ins. Accordingly, we are subject to all of the risks associated with owning and leasing real estate. In particular, the value of our
assets could decrease and our costs could increase because of changes in the investment climate for real estate, demographic trends and supply or demand for the use of our drive-ins, which may result from competition from similar restaurants in the
area, as well as liability for environmental conditions. We generally cannot cancel the leases, so if an existing or future Sonic Drive-In is not profitable, and we decide to close it, we may nonetheless be committed to perform our obligations under
the applicable lease including, among other things, paying the base rent for the balance of the lease term. In addition, as each of the leases expires, we may fail to negotiate renewals, either on commercially acceptable terms or at all, which could
cause us to close drive-ins in desirable locations.

Catastrophic events may disrupt our business.

Unforeseen events, or the prospect of such events, including war, terrorism and other international conflicts, public health issues
including health epidemics or pandemics, and natural disasters such as hurricanes, earthquakes, or other adverse weather and climate conditions, whether occurring in the United States or abroad, could disrupt our operations, disrupt the operations
of franchisees, suppliers or customers, or result in political or economic instability. These events could reduce demand for our products or make it difficult or impossible to receive products from suppliers.

Item 1B. Unresolved Staff Comments

None.

Item 2. Properties

Of the 455 Company-owned Drive-Ins operating as of August 31, 2010, we operated 204 of them on property leased from third-parties and 251 of them on property we own. The leases expire on dates
ranging from 2011 to 2027, with the majority of the leases providing for renewal options. All leases provide for specified monthly rental payments, and some of the leases call for additional rentals based on sales volume. All leases require Sonic to
maintain the property and pay the cost of insurance and taxes. We also own the real property on which 176 Franchise Drive-Ins are operated. These leases for Franchise Drive-Ins expire on dates ranging from 2012 to 2029, with the majority of the
leases providing for renewal options. The majority of the leases for Franchise Drive-Ins provide for percentage rent based on sales volume, with a minimum base rent. These leases generally require the franchisee to maintain the property and pay the
costs of insurance and taxes.

Our corporate headquarters are located in the Bricktown district of downtown Oklahoma City. We
have a 15-year lease to occupy approximately 83,000 square feet. The lease expires in November 2018 and has two five-year renewal options. Sonic believes its properties are suitable for the purposes for which they are being used.

Item 3. Legal Proceedings

The Company is involved in various legal proceedings and has certain unresolved claims pending. Based on the information currently available, management believes that all claims currently pending are
either covered by insurance or would not have a material adverse effect on the Companys business or financial condition.

Item 4. Submission of Matters to a Vote of Security Holders

Sonic did not submit any matter during the fourth
quarter of the Companys last fiscal year to a vote of Sonics stockholders through the solicitation of proxies or otherwise.

Item 7. Managements Discussion and Analysis of Financial Condition and Results of Operations

Overview

Description of the Business.Sonic operates and franchises the largest chain of drive-in restaurants in the United States. As of August 31, 2010, the Sonic system was comprised of 3,572
drive-ins, of which 13% were Company-owned Drive-Ins and 87% were Franchise Drive-Ins. Sonic Drive-Ins feature signature menu items such as specialty drinks and frozen desserts, made-to-order sandwiches and a unique breakfast menu. The Company
derives revenues primarily from Company-owned Drive-In sales and royalties from franchisees. The Company also receives revenues from leasing real estate to franchisees, initial franchise fees, earnings from minority investments in franchise
operations and other miscellaneous revenues.

Costs of Company-owned Drive-In sales relate directly to Company-owned Drive-In
sales. Other expenses, such as depreciation, amortization, and general and administrative expenses, relate to the Companys franchising operations, as well as Company-owned Drive-In operations. Our revenues and expenses are directly affected by
the number and sales volumes of Company-owned Drive-Ins. Our revenues and, to a lesser extent, expenses also are affected by the number and sales volumes of Franchise Drive-Ins. Initial franchise fees and franchise royalties are directly affected by
the number of Franchise Drive-In openings. Lease revenues are generated by leasing of land and buildings for Company-owned Drive-Ins that have been sold to franchisees.

Overview of Business Performance.Persistent unemployment and declines in consumer spending were the primary contributors to a challenging year. In the second quarter of fiscal year 2010,
sales were adversely affected by severe winter weather. While the second quarter is typically the Companys most volatile quarter, harsh weather, particularly in our core markets, contributed to a significant decline in same-store sales during
the quarter.

Throughout fiscal years 2010 and 2009, we implemented a number of initiatives to improve the customer experience
and emphasize Sonics core brand strengths such as high-quality food, new product news and service differentiation with skating carhops. In addition, a new targeted media allocation strategy and new messaging were implemented this past year to
communicate our brand effectively to the customer.

While the number of new store openings in fiscal year 2010 was down
compared to fiscal year 2009, investments by franchisees in new and existing locations continued throughout the year. Franchisees opened 80 new drive-ins and relocated or rebuilt 23 existing drive-ins during the fiscal year. We also opened the first
Sonic Drive-Ins in several new markets, including Connecticut.

The growth and success of our business is built around
implementation of our brand strategy, which features the following components:



| |  |  | Improved performance of Company-owned Drive-Ins, including consistent and improved operations execution, improved speed of service, cleanliness of
drive-ins, and focus on the customer experience; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Same-store sales growth fueled by re-emphasizing the Companys core brand strengths, including consistent drive-in execution, high-quality
products, new products and service differentiation with skating carhops.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The following table provides
information regarding the number of Company-owned Drive-Ins and Franchise Drive-Ins in operation as of the end of the years indicated as well as the system-wide growth in sales and average unit volume. System-wide information includes both
Company-owned Drive-In and Franchise Drive-In information, which we believe is useful in analyzing the growth of the brand as well as the Companys revenues, since franchisees pay royalties based on a percentage of sales.

System-wide same-store sales decreased 7.8% during fiscal year 2010 primarily as a result of a reduction in traffic (number of transactions per drive-in). The second fiscal quarter was adversely affected
by the severe weather in our core markets and accounted for an estimated two-thirds of the decline in same store sales during that time period. In the second half of the year, the Company implemented initiatives designed to provide a unique and high
quality customer service experience with the goal of improving same-store sales by driving both traffic and average check. These initiatives include focusing on customer service, offering differentiated high quality food and drink products, a new
value strategy, new commercials and implementation of a new media strategy.

During fiscal year 2010, our system-wide media
expenditures were approximately $167 million as compared to $184 million in fiscal year 2009. During the fiscal year, we modified our media strategy by shifting a larger portion of our marketing expenditures from national to local markets. We use
varying forms of advertising mediums, such as outdoor billboard, local radio and television and local store advertising to optimize media impressions in drive-in trade areas. We also continue to invest in system-wide marketing fund efforts, which
are largely used for network cable television advertising. Expenditures for national cable advertising decreased from approximately $96 million in fiscal year 2009 to approximately $72 million in fiscal year 2010, which was a result of the focus on
local markets and the decline in system-wide sales. Looking forward, we expect system-wide media expenditures to be approximately $170 million in fiscal 2011.

The following table provides information regarding drive-in development across the system.

For fiscal year 2010, the decrease in Company-owned Drive-In sales was largely driven by 245 drive-ins that were refranchised or closed since the beginning of fiscal year 2009 and the decline in
same-store sales for existing drive-ins. Drive-ins that were refranchised or closed resulted in $121.3 million of the decrease in fiscal year 2010, partially offset by sales of $4.9 million from drive-ins opened during the period. Same-store sales
decreases for existing drive-ins of $36.7 million were driven by the impact of weather previously discussed as well as a reduction of consumer spending at restaurants.

During fiscal year 2010, same-store sales at Company-owned Drive-Ins declined 8.8%, as compared to the 7.8% decrease for the system. In addition to implementation of system-wide initiatives, we
restructured management of our Company-owned Drive-In operations to reduce excess management layers, revised the compensation program at the drive-in level, and implemented a customer service initiative to improve sales and profits. During the
second half of the year, Company-owned Drive-Ins showed improvement in closing the gap in same-store sales growth with the Franchise Drive-Ins. These efforts are expected to have a continued positive impact on Company-owned Drive-In sales going
forward.

Sales at Company-owned Drive-Ins decreased 15.5% in fiscal year 2009, primarily due to 219 drive-ins that were
refranchised or closed during the year, which resulted in $100.9 million of the decrease, partially offset by sales of $11.8 million from drive-ins opened during the period. Same-store sales decreases of 6.4% for existing stores accounted for the
balance of the decrease in fiscal year 2009.

The following table reflects the growth in franchise income (franchise royalties
and franchise fees) as well as franchise sales, average unit volumes and the number of Franchise Drive-Ins. While we do not record Franchise Drive-In sales as revenues, we believe this information is important in understanding our financial
performance since these sales are the basis on which we calculate and record franchise royalties. This information is also indicative of the financial health of our franchisees.

Franchise royalties declined $4.3 million or 3.4% in fiscal year 2010 as compared to fiscal year 2009. Same-store sales decreases combined with a lower effective royalty rate resulted in a decrease in
royalties of $11.5 million, which was partially offset by $7.2 million in incremental royalties from newly constructed and refranchised drive-ins. The lower effective royalty rate resulted from the Companys variable royalty rate structure
which increases as same-store sales increase and decreases as same-store sales decrease. Franchise royalties increased 4.1% or $4.8 million in fiscal year 2009 as compared to fiscal year 2008 as a result of an $8.1 million increase from newly
constructed or refranchised stores, which was partially offset by the impact of declining same-store sales.

declined $2.3 million to $2.8 million in fiscal year 2010 as franchisees opened 80 new drive-ins, down from 130 new drive-ins in fiscal year 2009. The decrease is primarily comprised of $1.8 million attributable to fewer new drive-in openings in
fiscal 2010 compared with fiscal year 2009, as well as $0.7 million in reduced fees associated with incentives for the development of new Sonic Drive-Ins. Franchisee investment in existing drive-ins continued during fiscal year 2010, and included
the relocation or rebuild of 23 drive-ins (versus 46 in the prior year). Franchise fees decreased 3.1% to $5.0 million during fiscal year 2009 as a result of fewer Franchise Drive-In openings, in addition to a decline in fees associated with the
termination of area development agreements.

Lease revenue increased 72.6% to $6.9 million in fiscal year 2010 from $4.0
million in fiscal year 2009. The increase relates primarily to lease revenue from refranchised drive-ins in which the Company retained ownership of the real estate. Lease revenue increased $2.5 million to $4.0 million in fiscal year 2009 as compared
to $1.5 million in fiscal year 2008 also primarily due to lease revenue from refranchised drive-ins in which the Company retained ownership of the real estate during the latter half of fiscal year 2009.

Other income increased 44.3% to $4.5 million in fiscal year 2010 from $3.1 million in fiscal year 2009 primarily due to a minority
ownership interest that we retained in the operations of 88 drive-ins that were refranchised in fiscal year 2009.

Operating
Expenses. The following table presents the overall costs of drive-in operations as a percentage of Company-owned Drive-In sales. Other operating expenses include direct operating costs such as marketing, telephone and utilities, repair and
maintenance, rent, property tax and other controllable expenses. Noncontrolling interests of Company-owned Drive-Ins are no longer included as a part of cost of sales in the consolidated income statement due to recent accounting guidance changes. We
have included noncontrolling interests for comparative purposes in the table below.

Restaurant-level margins decreased overall in fiscal year 2010 as a result of higher labor costs
driven by minimum wage increases and the de-leveraging impact of lower same-store sales. In the third quarter of fiscal 2010, the Company implemented a new compensation program for Company-owned Drive-Ins as an alternative to the ownership program
to attract and retain quality talent. The new compensation program provides managers and supervisors a larger portion of guaranteed compensation but retains a significant incentive component based on drive-in level performance. As of April 2010,
most Company-owned Drive-Ins operate under this new compensation structure. These efforts are expected to have a positive impact for Company-owned Drive-In sales and profits in the long run but are expected to add 50 to 75 basis points to payroll
and other employee benefits on an annualized basis. In addition, the annual amounts of manager and supervisor bonuses have been reclassified from other operating expenses to payroll and other employee benefits. Manager and supervisor bonuses are
paid monthly and generally follow the seasonality in our business. Historically, under our previous compensation structure, these bonuses were classified as other operating expenses because they related to the profitability of individual stores for
equity partners.

Selling, General and Administrative (SG&A). SG&A expenses increased 5.5%
to $66.8 million during fiscal year 2010 and 3.6% to $63.4 million during fiscal year 2009. The increase for fiscal year 2010 is primarily attributable to $2.9 million in provision for bad debt expenses, as well as professional fees associated with
financial restructuring services for franchisees. Stock-based compensation is included in SG&A, and, as of August 31, 2010, total remaining unrecognized compensation cost related to unvested stock-based arrangements was $12.3 and is
expected to be recognized over a weighted average period of 1.7 years. See Note 1 and Note 13 of the Notes to the Consolidated Financial Statements included in this Form 10-K for additional information regarding our stock-based compensation.

Depreciation and Amortization. Depreciation and amortization expense decreased 11.3% to $42.6 million in fiscal
year 2010 and decreased 5.1% to $48.1 million in fiscal year 2009 primarily as a result of refranchising Company-owned Drive-Ins in fiscal year 2009. Capital expenditures during fiscal year 2010 were $24.5 million. For fiscal year 2011, capital
expenditures are expected to be approximately $20 to $25 million.

Provision for
Impairment of Long-Lived Assets. The Company identified impairments for certain drive-in assets and surplus property through regular quarterly reviews of long-lived assets. The recoverability of Company-owned Drive-Ins is assessed by
estimating the undiscounted net cash flows expected to be generated over the remaining life of the Company-owned Drive-Ins. This involves estimating same-store sales and margins for the cash flows period. The amount of impairment, if any, is
measured based on projected discounted future net cash flows. When impairment exists, the carrying value of the asset is written down to fair value.

In fiscal year 2010, we recorded a non-cash impairment of long-lived assets of $15.2 million to reduce the carrying cost of the related operating assets to an estimated fair value. This provision was
attributable to lower sales and profits in Company-owned Drive-Ins due to the sustained economic downturn and weaker results than anticipated during the summer months for operating stores. Assets impaired included operating drive-ins, property
leased to franchisees, surplus property and other assets. The decision whether to close or continue to operate a drive-in is made independent of the impairment process. We continue to perform quarterly analyses of certain underperforming drive-ins.
It is reasonably possible that the estimate of future cash flows associated with these drive-ins could change in the future resulting in the need to write-down to fair value assets associated with one or more of these drive-ins. While it is
impossible to predict if future write-downs will occur, we do not believe that future write-downs will impede our ability to grow earnings.

Interest Expense and Other Expense, Net. The net interest expense increase from fiscal year 2009 to fiscal year 2010 is a result of a $6.4 million gain from the early extinguishment of debt
that resulted from purchasing a portion of the Companys fixed rate notes at a discount in fiscal year 2009. Excluding this gain in fiscal year 2009, net interest expense decreased by $6.0 million from fiscal year 2009 to fiscal year 2010,
reflecting declining debt from amortization payments and a debt purchase of $58 million in the third quarter of the fiscal year. Net interest expense decreased $12.3 million to $35.7 million in fiscal year 2009. Of this decline, $6.4 million is
attributable to the gain from the early extinguishment of debt in fiscal year 2009.

Income Taxes. The provision
for income taxes decreased for fiscal year 2010 with an effective federal and state tax rate of 29.7% compared with 38.4% in fiscal year 2009 and 37.4% in fiscal year 2008. The decline in the tax rate for the fiscal year 2010 was primarily related
to a $1.8 million tax benefit associated with the stock option exchange program that was implemented in the third quarter of fiscal year 2010. Our tax rate may continue to vary significantly from quarter to quarter depending on the timing of option
exercises and dispositions by option holders, changes to uncertain tax positions and as circumstances on various tax matters change.

Noncontrolling Interests. Effective April 1, 2010, the Company introduced a new compensation program for managers and supervisors at Company-owned Drive-Ins as an alternative to the
traditional ownership program. As a result, compensation costs that were formerly reflected as noncontrolling interests are now included in payroll and other employee benefits. Primarily due to this change, noncontrolling interests decreased 69.8%
to $4.6 million for fiscal year 2010.

Financial Position

During fiscal year 2010, current assets decreased 33.7% to $133.9 million compared to $202.1 million as of the end of fiscal year 2009. Cash balances decreased by $51.6 million primarily as a result of
the purchase of $58.0 million in the Companys debt. During fiscal year 2010, noncurrent assets decreased 6.7% to $603.3 million compared to $646.9 million as of the end of fiscal year 2009. The decrease was primarily the result of a $34.7
million reduction of net property and equipment resulting from depreciation and the refranchising of Company-owned Drive-Ins.

Total liabilities decreased $136.6 million or 16.0% during fiscal year 2010 compared to fiscal year 2009 primarily due to a $107.9
million decrease in long-term debt which resulted from scheduled payments on the Companys fixed rate notes in addition to the debt purchase mentioned above.

Stockholders equity increased $24.9 million during fiscal year 2010. The increase primarily relates to earnings of $21.2 million, along with a $4.7 million net increase in paid-in capital related to
stock compensation and the repurchase of noncontrolling interests in Company-owned Drive-Ins resulting from changes in the ownership program.

Liquidity and Sources of Capital

Operating Cash Flows.Net cash provided by operating activities decreased by $19.9 million from $97.5
million in fiscal year 2009 to $77.6 million in fiscal year 2010. Of the total decrease, approximately $11 million relates to the refranchising of 205 Company-owned Drive-Ins in fiscal 2009 and 16 Company-owned Drive-Ins in fiscal 2010, partially
offset by $8 million in cash flow from royalties and lease revenue from the refranchised drive-ins. In addition, $12.5 million of the decrease in net cash provided by operating activities resulted from current-year tax payments in excess of those
paid in the previous fiscal year. The balance relates to a decline in cash flow from operations of Company-owned Drive-Ins and lower franchise income due primarily to the difficult economic environment.

Investing Cash Flows.Net cash used in investing activities was $9.4 million in fiscal year 2010 as compared to net cash
provided by investing activities of $49.2 million in fiscal year 2009. The $58.6 million decrease primarily relates to a decrease in proceeds from the sale of assets of $70.7 million related to refranchising drive-ins in fiscal years 2009 and 2010,
partially offset by a decrease of $11.7 million in purchases of property and equipment. Five Company-owned Drive-Ins were constructed and opened during fiscal year 2010. The following table sets forth the components of our investments in capital
additions for fiscal year 2010 (in millions):



|                                                                    |  |   |      |

Financing Cash Flows.Net cash used in financing activities was $119.8 million in fiscal year
2010 as compared to $53.4 million in fiscal year 2009. The increase in cash used for financing activities in fiscal year 2010 as compared to fiscal year 2009 primarily relates to the repayment of long-term debt combined with a $12.5 million
reduction in proceeds from borrowings in fiscal year 2010.

The Company has a securitized financing facility of variable
funding notes that provides for the issuance of up to $200.0 million in borrowings and certain other credit instruments, including letters of credit. As of August 31, 2010, our outstanding balance under the variable funding notes totaled $187.3
million at an effective borrowing rate of 1.4%, as well as $0.3 million in outstanding letters of credit. During fiscal year 2009, upon request of the Company to draw down the remaining $12.3 million in variable funding notes from one of the
lenders, the lender, which had previously filed for Chapter 11 bankruptcy, notified the Company that it could not meet its obligation. At this time, the Company does not consider the $12.3 million to be available. Subsequent to August 31, 2010,
the credit rating for the Companys variable and fixed rate notes was downgraded by Standard & Poors. As a result of the downgrade, the Company will be required to pay an additional 0.5% premium to the company that guarantees
payment of the debt.

Despite recent challenges with Company-owned Drive-In operations, operating cash flows remain healthy,
and we believe that cash flows from operations, along with existing cash balances, will be adequate for mandatory repayment of any long-term debt and funding of planned capital expenditures in fiscal year 2011. See Note 10 of the Notes to
Consolidated Financial Statements for additional information regarding our long-term debt.

Our variable and fixed rate notes
are subject to a series of covenants and restrictions customary for transactions of this type, including (i) required actions to better secure collateral upon the occurrence of certain performance-related events, (ii) application of
certain disposition proceeds as note prepayments after a set time is allowed for reinvestment, (iii) maintenance of specified reserve accounts, (iv) maintenance of certain debt service coverage ratios, (v) optional and mandatory
prepayments upon change in control, (vi) indemnification payments for defective or ineffective collateral, and (vii) covenants relating to recordkeeping, access to information and similar matters. If certain covenants or restrictions are
not met, the notes are subject to customary rapid amortization events and events of default. Although management does not anticipate an event of default or any other event of noncompliance with the provisions of the debt, if such an event occurred,
the unpaid amounts outstanding could become immediately due and payable. See Note 1  Restricted Cash of the Notes to Consolidated Financial Statements for additional information regarding restrictions on cash.

We plan capital expenditures of approximately $20 to $25 million in fiscal year 2011. These capital expenditures primarily relate to the
development of additional Company-owned Drive-Ins, retrofit of existing Company-owned Drive-Ins and other drive-in level expenditures, as well as technology infrastructure expenditures. We expect to fund these capital expenditures through cash flow
from operations as well as cash on hand.

As of August 31,
2010, our unrestricted cash balance of $86.0 million reflected the impact of the cash generated from operating activities, borrowing activity, refranchising, and capital expenditures mentioned above. We believe that existing cash and funds generated
from operations, as well as borrowings under the variable funding notes, will meet our needs for the foreseeable future.

Off-Balance Sheet
Arrangements

The Company has obligations for guarantees on certain franchisee loans and lease agreements. See Note 17 of
the Notes to Consolidated Financial Statements for additional information about these guarantees. Other than such guarantees and various operating leases, which are disclosed more fully in Contractual Obligations and Commitments below
and Note 7 to our Consolidated Financial Statements, the Company has no other material off-balance sheet arrangements.

Contractual

Impact of Inflation

We have experienced impact from inflation. Inflation
has caused increased food, labor and benefits costs and has increased our operating expenses. To the extent permitted by competition, increased costs are recovered through a combination of menu price increases and reviewing, then implementing,
alternative products or processes, or by implementing other cost reduction procedures.

Critical Accounting Policies and Estimates

The Consolidated Financial Statements and Notes to Consolidated Financial Statements included in this document contain
information that is pertinent to managements discussion and analysis. The preparation of financial statements in conformity with generally accepted accounting principles requires management to use its judgment to make estimates and assumptions
that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities. These assumptions and estimates could have a material effect on our financial statements. We evaluate our assumptions and estimates on an
ongoing basis using historical experience and various other factors that are believed to be relevant under the circumstances. Actual results may differ from these estimates under different assumptions or conditions.

We annually review our financial reporting and disclosure practices and accounting policies to ensure that our financial reporting and
disclosures provide accurate and transparent information relative to the current economic and business environment. We believe that of our significant accounting policies (see Note 1 of Notes to Consolidated Financial Statements) the following
policies involve a higher degree of risk, judgment and/or complexity.

##### Table of Contents



Impairment of
Long-Lived Assets.We review Company-owned Drive-In assets for impairment when events or circumstances indicate they might be impaired. We test for impairment using historical cash flows and other relevant facts and
circumstances as the primary basis for our estimates of future cash flows. This process requires the use of estimates and assumptions, which are subject to a high degree of judgment. These impairment tests require us to estimate fair values of
our drive-ins by making assumptions regarding future cash flows and other factors. During fiscal year 2010, we reviewed Company-owned Drive-Ins and other long-lived assets with combined carrying amounts of $57 million in property, equipment and
capital leases for possible impairment, and our cash flow assumptions resulted in impairment charges totaling $15.2 million to write down certain assets to their estimated fair value.

We assess the recoverability of goodwill and other intangible assets related to our brand and drive-ins at least annually and more
frequently if events or changes in circumstances occur indicating that the carrying amount of the asset may not be recoverable. Goodwill impairment testing first requires a comparison of the fair value of each reporting unit to the carrying value.
We estimate fair value based on a comparison of two approaches: discounted cash flow analyses and a market multiple approach. The discounted estimates of future cash flows include significant management assumptions such as revenue growth rates,
operating margins, weighted average cost of capital, and future economic and market conditions. In addition, the market multiple approach includes significant assumptions such as the use of recent historical market multiples to estimate future
market pricing. These assumptions are significant factors in calculating the value of the reporting units and can be affected by changes in consumer demand, commodity pricing, labor and other operating costs, our cost of capital and our ability
to identify buyers in the market. If the carrying value of the reporting unit exceeds fair value, goodwill is considered impaired. The amount of the impairment is the difference between the carrying value of the goodwill and the
implied fair value, which is calculated as if the reporting unit had just been acquired and accounted for as a business combination.

During the fourth quarter of fiscal year 2010, we performed our annual assessment of recoverability of goodwill and other intangible assets and determined that no impairment was indicated. As of the
impairment testing date, the fair value of the Company-owned Drive-In reporting unit exceeded the carrying value by approximately 21.4%. The carrying value of goodwill as of August 31, 2010, was $82.1 million, all of which was allocated to the
Company-owned Drive-In reporting unit. If cash flows generated by our Company-owned Drive-Ins were to decline significantly in the future or there were negative revisions to key assumptions, we may be required to record impairment charges to reduce
the carrying amount of goodwill.

Ownership Program.Effective April 1, 2010, the Company
introduced a new compensation program as an alternative to the prior form of ownership to improve manager and supervisor retention. While managers and supervisors do not own an interest in their drive-ins under the new compensation program, the
compensation program provides managers and supervisors a larger portion of guaranteed compensation, but retains a significant incentive component based on drive-in level performance. Prior to April 1, 2010, the drive-in management compensation
program was structured as an ownership program. As part of the ownership program, either a limited liability company or a general partnership was formed to own and operate each individual Company-owned Drive-In. SRI owned a controlling ownership
interest, typically at least 60%, in each of these limited liability companies and partnerships. Generally, the supervisors and managers owned a noncontrolling interest in the limited liability company or partnership. As owners, they shared in the
cash flow and were responsible for their share of any losses incurred by their Company-owned Drive-Ins.

The Company records
the earnings related to noncontrolling interests of supervisors and managers as net income attributable to non-controlling interests below net income. As a result of the change to our compensation program for Company-owned Drive-Ins,
compensation costs that were formerly reflected in noncontrolling interests and other operating expenses are now included in payroll and other employee benefits.

Revenue Recognition Related to Franchise Fees and Royalties. Initial franchise fees are recognized in income when we have substantially performed or satisfied all material services or
conditions relating to the sale of the franchise and the fees are nonrefundable. Area development fees are nonrefundable and are recognized in income on a pro-rata basis when the conditions for revenue recognition under the individual area
development agreements are met. Both initial franchise fees and area development fees are generally recognized upon the opening of a Franchise Drive-In or upon termination of the agreement between Sonic and the franchisee.

Our franchisees are
required under the provisions of the license agreements to pay royalties to Sonic each month based on a percentage of actual net sales. However, the royalty payments and supporting financial statements are not due until the following month under the
terms of our license agreements. As a result, we accrue royalty revenue in the month earned based on polled sales of Franchise Drive-Ins and sales estimates for nonpolling drive-ins.

Accounting for Stock-Based Compensation. We account for stock-based compensation in accordance with Accounting Standards
Codification (ASC) Topic 718, Stock Compensation. We estimate the fair value of options granted using the Black-Scholes option pricing model along with the assumptions shown in Note 13 of Notes to the Consolidated Financial Statements in this Form
10-K. The assumptions used in computing the fair value of stock-based payments reflect our best estimates, but involve uncertainties relating to market and other conditions, many of which are outside of our control. We estimate expected volatility
based on historical daily price changes of the Companys stock for a period equal to the current expected term of the options. The expected option term is the number of years the Company estimates that options will be outstanding prior to
exercise considering vesting schedules and our historical exercise patterns. If other assumptions or estimates had been used, the stock-based compensation expense that was recorded during fiscal year 2010 could have been materially different.
Furthermore, if different assumptions are used in future periods, stock-based compensation expense could be materially impacted.

Income Taxes. We estimate certain components of our provision for income taxes. These estimates include, among other items, depreciation and amortization expense allowable for tax purposes,
allowable tax credits for items such as wages paid to certain employees, effective rates for state and local income taxes and the tax deductibility of certain other items.

We account for uncertain tax positions under ASC Topic 740, Income Taxes, which sets out criteria for the use of judgment in assessing the timing and amounts of deductible and taxable items. Although we
believe we have adequately accounted for our uncertain tax positions, from time to time, audits result in proposed assessments where the ultimate resolution may give rise to us owing additional taxes. We adjust our uncertain tax positions in light
of changing facts and circumstances, such as the completion of a tax audit, expiration of a statute of limitations, the refinement of an estimate, and penalty and interest accruals associated with uncertain tax positions until they are resolved. We
believe that our tax positions comply with applicable tax law and that we have adequately provided for these matters. However, to the extent that the final tax outcome of these matters is different than the amounts recorded, such differences will
impact the provision for income taxes in the period in which such determination is made.

Our estimates are based on the best
available information at the time that we prepare the provision, including legislative and judicial developments. We generally file our annual income tax returns several months after our fiscal year end. Income tax returns are subject to audit by
federal, state and local governments, typically several years after the returns are filed. These returns could be subject to material adjustments or differing interpretations of the tax laws. Adjustments to these estimates or returns can result in
significant variability in the tax rate from period to period.

Leases. We lease the land and buildings for
certain Company-owned Drive-Ins from third parties. Rent expense for operating leases is recognized on a straight-line basis over the expected lease term, including cancelable option periods when it is deemed to be reasonably assured that we would
incur an economic penalty for not exercising the options. Judgment is required to determine options expected to be exercised. Certain of our leases have provisions for rent holidays and/or escalations in payments over the base lease term, as well as
renewal periods. The effects of the rent holidays and escalations are reflected in rent expense on a straight-line basis over the expected lease term, including cancelable option periods when appropriate. The lease term commences on the date when we
have the right to control the use of lease property, which can occur before rent payments are due under the terms of the lease. Contingent rent is generally based on sales levels and is accrued at the point in time we determine that it is probable
that such sales levels will be achieved.

Item 7A. Quantitative and Qualitative Disclosures About Market
Risk

Sonics use of debt directly exposes the Company to interest rate risk. Floating rate debt, where the
interest rate fluctuates periodically, exposes the Company to short-term changes in market interest rates. Fixed rate debt, where the interest rate is fixed over the life of the instrument, exposes the Company to changes in market interest rates
reflected in the fair value of the debt and to the risk that the Company may need to refinance maturing debt with new debt at a higher rate. Sonic is also exposed to market risk from changes in commodity prices. Sonic does not utilize financial
instruments for trading purposes. Sonic manages its debt portfolio to achieve an overall desired position of fixed and floating rates and may employ interest rate swaps as a tool to achieve that goal in the future.

##### Table of Contents



Interest Rate
Risk. Our exposure to interest rate risk at August 31, 2010 is primarily based on the fixed rate notes with an effective rate of 5.7%, before amortization of debt-related costs. At August 31, 2010, the fair value of the fixed rate
notes was estimated at $388 million versus carrying value of $404.0 million (including accrued interest). The difference between fair value and carrying value is attributable to interest rate decreases subsequent to when the debt was originally
issued, more than offset by the increase in credit spreads required by issuers of similar debt instruments in the current market. Should interest rates and/or credit spreads increase or decrease by one percentage point, the estimated fair value of
the fixed rate notes would decrease by approximately $7.0 million or increase by approximately $7.2 million, respectively. The fair value estimate required significant assumptions by management as there are few, if any, securitized loan transactions
occurring in the current market. Management used market information available for public debt transactions for companies with ratings that are close to or lower than ratings for the Company (without consideration for the third-party credit
enhancement). Management believes this fair value is a reasonable estimate with the information that is available.

The
variable funding notes outstanding at August 31, 2010 totaled $187.3 million, with a variable rate of 1.4%. The annual impact on our results of operations of a one-point interest rate change for the balance outstanding at year-end would be
approximately $1.9 million before tax. At August 31, 2010, the fair value of the variable funding notes was estimated at $164 million versus carrying value of $187.3 million (including accrued interest). Should credit spreads increase or
decrease by one percentage point, the estimated fair value of the variable funding notes would decrease by approximately $3.7 million or increase by approximately $3.8 million, respectively. The Company used similar assumptions to value the variable
funding notes as were used for the fixed rate notes. The difference between fair value and carrying value is attributable to the increase in credit spreads required by issuers of similar debt instruments in the current market.

We have made certain loans to our franchisees totaling $8.7 million as of August 31, 2010. The interest rates on these notes are
generally between 3.3% and 10.5%. We believe the carrying amount of these notes approximates their fair value.

Commodity Price Risk. The Company and its franchisees purchase certain commodities such as beef, potatoes, chicken and
dairy products. These commodities are generally purchased based upon market prices established with vendors. These purchase arrangements may contain contractual features that limit the price paid by establishing price floors or caps; however, we
have not made any long-term commitments to purchase any minimum quantities under these arrangements. We do not use financial instruments to hedge commodity prices because these purchase agreements help control the ultimate cost.

This market risk discussion contains forward-looking statements. Actual results may differ materially from this discussion based upon
general market conditions and changes in financial markets.

Managements
Report on Internal Control over Financial Reporting

The management of the Company is responsible for establishing and
maintaining adequate internal control over financial reporting. The Companys internal control system was designed to provide reasonable assurance to the Companys management and Board of Directors regarding the preparation and fair
presentation of published financial statements. All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to
financial statement preparation and presentation.

The Companys management assessed the effectiveness of the
Companys internal control over financial reporting as of August 31, 2010. In making this assessment, it used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal
ControlIntegrated Framework. Based on our assessment, we believe that, as of August 31, 2010, the Companys internal control over financial reporting is effective based on those criteria.

The Companys independent registered public accounting firm that audited the financial statements included in the annual report has
issued an attestation report on the Companys internal control over financial reporting. This report appears on the following page.

Report of
Independent Registered Public Accounting Firm

The Board of Directors and Stockholders of Sonic Corp.

We have audited Sonic Corp.s internal control over financial reporting as of August 31, 2010, based on criteria established in
Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Sonic Corp.s management is responsible for maintaining effective internal control over financial
reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Managements Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on
the companys internal control over financial reporting based on our audit.

We conducted our audit in accordance with
the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was
maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of
internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A companys internal control over financial reporting is a process designed to provide reasonable assurance regarding the
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A companys internal control over financial reporting includes those policies and
procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are
recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management
and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the companys assets that could have a material effect on the financial
statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect
misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may
deteriorate.

In our opinion, Sonic Corp. maintained, in all material respects, effective internal control over financial
reporting as of August 31, 2010, based on the COSO criteria.

We also have audited, in accordance with the standards of
the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Sonic Corp. as of August 31, 2010 and 2009, and the related consolidated statements of income, stockholders equity (deficit), and cash flows
for each of the three years in the period ended August 31, 2010 of Sonic Corp. and our report dated October 29, 2010 expressed an unqualified opinion thereon.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders of

Sonic Corp.

We have audited the accompanying
consolidated balance sheets of Sonic Corp. as of August 31, 2010 and 2009, and the related consolidated statements of income, stockholders equity (deficit), and cash flows for each of the three years in the period ended August 31,
2010. Our audits also included the financial statement schedule listed in the Index at Item 15. These financial statements and schedule are the responsibility of the Companys management. Our responsibility is to express an opinion on
these financial statements and schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test
basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to
above present fairly, in all material respects, the consolidated financial position of Sonic Corp. at August 31, 2010 and 2009, and the consolidated results of their operations and their cash flows for each of the three years in the period
ended August 31, 2010, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents
fairly in all material respects the information set forth therein.

We also have audited, in accordance with the standards of the Public
Company Accounting Oversight Board (United States), the effectiveness of Sonic Corp.s internal control over financial reporting as of August 31, 2010, based on criteria established in Internal Control-Integrated Framework issued by the
Committee of Sponsoring Organizations of the Treadway Commission and our report dated October 29, 2010, expressed an unqualified opinion thereon.

As discussed in Note 1 to the consolidated financial statements, in fiscal year 2010 the Company adopted Accounting Standards Certification Topic 810 Consolidation.

Sonic Corp.

Notes to Consolidated Financial Statements

August 31, 2010, 2009
and 2008

(In Thousands, Except Per Share Data)

1. Summary of Significant Accounting Policies

Operations

Sonic Corp. (the Company) operates and franchises a chain of quick-service drive-ins in the United States. It derives its revenues primarily
from Company-owned Drive-In sales and royalty fees from franchisees. The Company also leases signs and real estate, and receives equity earnings in noncontrolling ownership in a number of Franchise Drive-Ins.

Principles of Consolidation

The
accompanying financial statements include the accounts of the Company, its wholly owned subsidiaries and its Company-owned Drive-Ins. All significant intercompany accounts and transactions have been eliminated.

Certain amounts have been reclassified in the Consolidated Financial Statements to conform to the fiscal year 2010 presentation.

Use of Estimates

The preparation of
consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported and contingent assets and liabilities disclosed
in the financial statements and accompanying notes. Actual results may differ from those estimates, and such differences may be material to the financial statements.

Cash Equivalents

Cash equivalents consist of highly liquid investments, primarily money
market accounts that mature in three months or less from date of purchase, and depository accounts.

Restricted Cash

As of August 31, 2010, the Company had restricted cash balances totaling $22,231 for funds required to be held in trust for the benefit of senior
note holders under the Companys debt arrangements. The current portion of restricted cash of $12,546 represents amounts to be returned to Sonic or paid to service current debt obligations. The noncurrent portion of $9,685 represents interest
reserves required to be set aside for the duration of the debt.

Accounts and Notes Receivable

The Company charges interest on past due accounts receivable at a rate of 18% per annum. Interest accrues on notes receivable based on contractual
terms. The Company monitors all accounts for delinquency and provides for estimated losses for specific receivables that are not likely to be collected. In addition, a general provision for bad debt is estimated based on historical trends.

Inventories

Inventories
consist principally of food and supplies that are carried at the lower of cost (first-in, first-out basis) or market.

Property, Equipment
and Capital Leases

Property and equipment are recorded at cost, and leased assets under capital leases are recorded at the present value
of future minimum lease payments. Depreciation of property and equipment and amortization of capital leases are computed by the straight-line method over the estimated useful lives or the lease term, including cancelable option periods when
appropriate, and are combined for presentation in the financial statements.

1. Summary of Significant Accounting Policies (continued)



Accounting for Long-Lived Assets

In accordance with Accounting Standards Codification (ASC) Topic 360, the Company reviews long-lived assets whenever events or changes in circumstances indicate that the carrying amount of an asset might
not be recoverable. Assets are grouped and evaluated for impairment at the lowest level for which there are identifiable cash flows that are largely independent of the cash flows of other groups of assets, which generally represents the individual
drive-in. The Companys primary test for an indicator of potential impairment is operating losses. If an indication of impairment is determined to be present, the Company estimates the future cash flows expected to be generated from the use of
the asset and its eventual disposal. If the sum of undiscounted future cash flows is less than the carrying amount of the asset, an impairment loss is recognized. The impairment loss is measured by comparing the fair value of the asset to its
carrying amount. Fair value is typically determined to be the value of the land, since drive-in buildings and improvements are single-purpose assets and have little value to market participants. The equipment associated with a store can be easily
relocated to another store, and therefore is not adjusted.

Surplus property assets are carried at the lower of depreciated cost or fair value
less cost to sell. The majority of the value in surplus property is land. Fair values are estimated based upon appraisals or independent assessments of the assets estimated sales values.

Goodwill and Other Intangible Assets

The Company accounts for goodwill and other intangible assets in accordance with ASC Topic 350. Goodwill is determined based on acquisition purchase price
in excess of the fair value of identified assets. Intangible assets with lives restricted by contractual, legal, or other means are amortized over their useful lives. The Company tests all goodwill and other intangible assets not subject to
amortization at least annually for impairment using the fair value approach on a reporting unit basis. The Companys reporting units are defined as Company-owned Drive-Ins and Franchise Operations (see additional information regarding the
Companys reporting units in Note 14, Segment Information). The accounting guidance requires a two-step process for testing impairment. We test for impairment using historical cash flows and other relevant facts and circumstances as the primary
basis for our estimates of future cash flows. This process requires the use of estimates and assumptions, which are subject to a high degree of judgment. These impairment tests require us to estimate fair values of our drive-ins by making
assumptions regarding future cash flows and other factors.

We assess the recoverability of goodwill and other intangible assets related to
our brand and drive-ins at least annually and more frequently if events or changes in circumstances occur indicating that the carrying amount of the asset may not be recoverable. Goodwill impairment testing first requires a comparison of the fair
value of each reporting unit to the carrying value. We estimate fair value based on a comparison of two approaches: discounted cash flow analyses and a market multiple approach. The discounted estimates of future cash flows include significant
management assumptions such as revenue growth rates, operating margins, weighted average cost of capital, and future economic and market conditions. In addition, the market multiple approach includes significant assumptions such as the use of recent
historical market multiples to estimate future market pricing. These assumptions are significant factors in calculating the value of the reporting units and can be affected by changes in consumer demand, commodity pricing, labor and other
operating costs, our cost of capital and our ability to identify buyers in the market. If the carrying value of the reporting unit exceeds fair value, goodwill is considered impaired. The amount of the impairment is the difference between the
carrying value of the goodwill and the implied fair value, which is calculated as if the reporting unit had just been acquired and accounted for as a business combination.

The Companys intangible assets subject to amortization consist primarily of acquired franchise agreements, franchise fees, and other intangibles. Amortization expense is calculated using the
straight-line method over the expected period of benefit, not exceeding 20 years. See Note 5 for additional disclosures related to goodwill and other intangibles.

1. Summary of Significant Accounting Policies (continued)



Ownership Structure

Company-owned Drive-Ins are drive-in operations in which the Companys operating subsidiary, Sonic Restaurants, Inc. (SRI), owns a controlling ownership interest. Historically,
Company-owned Drive-Ins have operated as individual limited liability companies or general partnerships in which the manager and the supervisor for the respective drive-in own a noncontrolling interest (generally, the ownership program).
Under the ownership program, managers and supervisors shared in the cash flow for their Company-owned Drive-In but were also responsible for their share of any losses incurred by the drive-in. Effective April 1, 2010, the Company introduced a
new compensation program as an alternative to the ownership program to improve retention. While partners and supervisors do not have an ownership interest in their drive-in(s) under the new compensation program, the program provides managers and
supervisors a larger portion of guaranteed compensation but retains a significant incentive component based on drive-in level performance. With this change, 95% of Company-owned Drive-Ins now operate under the new compensation structure.

For those Company-owned Drive-Ins still in the Companys ownership program, noncontrolling interests are recorded as a component of equity on the
Consolidated Balance Sheets, and our partners share of the drive-in earnings are reflected as net incomenoncontrolling interests on the Consolidated Statements of Income. The ownership agreements contain provisions that give the Company
the right, but not the obligation, to purchase the noncontrolling interest of the supervisor or manager in a drive-in. The amount of the investment made by a partner and the amount of the buy-out are based on a number of factors, including primarily
the drive-ins financial performance for the preceding 12 months, and are intended to approximate the fair value of a noncontrolling interest in the drive-in.

Under the ownership program, the Company acquires noncontrolling interests in Company-owned Drive-Ins as managers and supervisors sell their ownership interests. If the purchase price of a noncontrolling
interest that we acquire exceeds the net book value of the assets underlying the partnership interest, the excess is recorded as paid-in capital. The acquisition of a noncontrolling interest for less than book value is recorded as a reduction in
paid-in capital.

Revenue Recognition, Franchise Fees and Royalties

Revenue from Company-owned Drive-In sales is recognized when food and beverage products are sold. Company-owned Drive-In sales are presented net of sales tax and other sales-related taxes.

Initial franchise fees are recognized in income when all material services or conditions relating to the sale of the franchise have been substantially
performed or satisfied by the Company and the fees are nonrefundable. Area development agreement fees are generally nonrefundable and are recognized in income on a pro rata basis when the conditions for revenue recognition under the individual area
development agreements are met. Both initial franchise fees and area development fees are generally recognized upon the opening of a Franchise Drive-In or upon termination of the agreement between the Company and the franchisee.

The Companys franchisees are required under the provisions of the license agreements to pay the Company royalties each month based on a percentage
of actual sales. However, the royalty payments and supporting financial statements are not due until the following month. As a result, the Company accrues royalty revenue in the month earned based on polled sales from Franchise Drive-Ins and sales
estimates for nonpolling drive-ins.

Operating Leases

Rent expense is recognized on a straight-line basis over the expected lease term, including cancelable option periods when it is deemed to be reasonably assured that the Company would incur an economic
penalty for not exercising the options. Within the provisions of certain of our leases, there are rent holidays and/or escalations in payments over the base lease term, as well as renewal periods. The effects of the holidays and escalations have
been reflected in rent expense on a straight-line basis over the expected lease term, which includes cancelable option periods when appropriate. The lease term commences on the date when the Company has the right to control the use of the leased
property, which can occur before rent payments are due under the terms of the lease. Percentage rent expense is generally based on sales levels and is accrued at the point in time it is probable that such sales levels will be achieved.

Advertising Costs

Costs incurred in connection with the advertising and promoting of the Companys products are included in other operating expenses and are expensed as incurred. Such costs amounted to $22,537,
$32,997, and $36,801 for fiscal years 2010, 2009 and 2008, respectively.

Under the Companys license agreements, both Company-owned
Drive-Ins and Franchise Drive-Ins must contribute a minimum percentage of revenues to a national media production fund (Sonic Brand Fund) and spend an additional minimum percentage of gross revenues on local advertising, either directly or through
Company-required participation in advertising cooperatives. A portion of the local advertising contributions is redistributed to a System Marketing Fund, which purchases advertising on national cable and broadcast networks and funds other national
media and sponsorship opportunities. As stated in the terms of existing license agreements, these funds do not constitute assets of the Company, and the Company acts with limited agency in the administration of these funds. Accordingly, neither the
revenues and expenses nor the assets and liabilities of the advertising cooperatives, the Sonic Brand Fund, or the System Marketing Fund are included in the Companys consolidated financial statements. However, all advertising contributions by
Company-owned Drive-Ins are recorded as expense on the Companys financial statements.

Stock-Based Compensation

In accordance with ASC Topic 718, stock-based compensation is measured at the grant date, based on the calculated fair value of the award, and is
recognized as an expense over the requisite employee service period (generally the vesting period of the grant).

The following table shows
total stock-based compensation expense and the tax benefit included in the Consolidated Statements of Income and the effect on basic and diluted earnings per share for the years ended August 31:

|                                     |  |      |        |   |      |   |        |      |  |   |        |  
|Impact on net income per share:      |  |      |        |   |      |   |        |      |  |   |        |  
|Basic                                |  | $    | 0.05   |   |      | $ | 0.07   |      |  | $ | 0.08   |  
|Diluted                              |  | $    | 0.05   |   |      | $ | 0.07   |      |  | $ | 0.07   |  

The Company grants both incentive and
non-qualified stock options. For grants of non-qualified stock options, the Company expects to recognize a tax benefit on exercise of the option, so the full tax benefit is recognized on the related stock-based compensation expense. For grants of
incentive stock options, a tax benefit only results if the option holder has a disqualifying disposition. As a result of the limitation on the tax benefit for incentive stock options, the tax benefit for stock-based compensation will generally be
less than the Companys overall tax rate, and will vary depending on the timing of employees exercises and sales of stock. However, in fiscal year 2010, the Company executed a stock option exchange which resulted in an additional tax
benefit of $1.8 million for the conversion of eligible incentive stock options to nonqualified stock options. Additional information regarding the stock option exchange program is provided in Note 13.

Income Taxes

Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their
respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax
assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

Income tax benefits
credited to equity relate to tax benefits associated with amounts that are deductible for income tax purposes but do not affect earnings. These benefits are principally generated from employee exercises of non-qualified stock options and
disqualifying dispositions of incentive stock options.

The threshold for recognizing the financial statement effects of a tax position when
it is more likely than not, based on the technical merits, that the position will be sustained upon examination by a taxing authority. Recognized tax positions are initially and subsequently measured as the largest amount of tax benefit that is more
likely than not to be realized upon ultimate settlement with a taxing authority. Liabilities for unrecognized tax benefits related to such tax positions are included in other long-term liabilities unless the tax position is expected to be settled
within the upcoming year, in which case the liabilities are included in accrued expenses and other current liabilities. Interest and penalties related to unrecognized tax benefits are included in income tax expense.

Additional information regarding the Companys unrecognized tax benefits is provided in Note 12.

Disclosures About Fair Value of Financial Instruments

ASC Topic 820 defines fair value, establishes a framework for its measurement and requires disclosures about fair value measurements. The framework provides a fair value hierarchy that prioritizes the
inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurement) and the lowest priority to unobservable
inputs (level 3 measurement). The three levels of the fair value hierarchy are described below:

Level 1Quoted prices in active markets
for identical assets or liabilities.

Level 2Other significant observable inputs (including quoted prices for similar securities,
interest rates, prepayment, credit risk, etc.).

Level 3Significant unobservable inputs.

The assets or liabilitys fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is
significant to the fair value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs.

Certain nonfinancial assets and liabilities are measured at fair value on a nonrecurring basis, which means these assets and
liabilities are not measured at fair value on an ongoing basis but are subject to periodic impairment tests. For the Company, these items primarily include long-lived assets, goodwill and other intangible assets. Refer to Accounting for
Long-Lived Assetsand Goodwill and Other Intangible Assets in Note 1 for inputs and valuation techniques used to measure the fair value of these nonfinancial assets. The fair value was based upon management assessment as well as
appraisals or independent assessments which involved Level 3 inputs. There was a $15.2 million charge recorded for fiscal year 2010 for the impairment of long-lived assets. See Note 3 for a description of the impairment.

Noncontrolling Interests

Effective
September 1, 2009, the Company implemented ASC Topic 810, Consolidation. Topic 810 requires noncontrolling interests, previously called minority interests, to be presented as a separate item in the equity section of the consolidated
balance sheet. It also requires the amount of consolidated net income attributable to noncontrolling interests to be clearly presented on the face of the consolidated income statement.

Additionally, Topic 810 clarifies that changes in a parents ownership interest in a subsidiary that do not result in deconsolidation are equity transactions, and that deconsolidation of a subsidiary
requires gain or loss recognition in net income based on the fair value on the deconsolidation date. Topic 810 was applied prospectively with the exception of presentation and disclosure requirements, which were applied retrospectively for all
periods presented, and did not significantly change the presentation of our consolidated financial statements.

Reclassifications

The Company buys and sells Company-owned Drive-Ins as a part of its ongoing business operations. Gains and losses derived from these
transactions have historically been reported net in other revenues on the Consolidated Statements of Income. The Company reported these net gains and losses in other operating income beginning in the third quarter of fiscal year 2010 and has
reclassified amounts previously reported in the current and prior fiscal years to conform to this new presentation.

On the Statements of Cash
Flows for fiscal year 2009, $8,881 was reclassified from a reduction of cash for the change in operating assets in cash flows from operations to a reduction of proceeds from disposition of assets, net of cash paid in cash flows from investing
activities. This reclassification relates to cash from the sale of real estate that was held in restricted cash for a period of time as required by the Companys debt agreement. In addition, the cash paid and received related to noncontrolling
interests in Company-owned Drive-Ins was reclassified from cash flows from investing activities to cash flows from financing activities in accordance with ASC Topic 810. The amount of cash paid for noncontrolling interests for fiscal year 2010 was
$9,277 as compared to $11,753 for the same period in fiscal year 2009. The amount of cash received for noncontrolling interests was $613 and $5,190 for fiscal years 2010 and 2009, respectively.

3. Assets Held for Sale and Impairment of Long-Lived Assets

Assets held for sale consist of Company-owned Drive-Ins that we expect to sell within one year. Such assets are classified as assets held for sale upon meeting the requirements of ASC Topic 360. These
assets are recorded at the lower of the carrying amount or fair value less costs to sell. Assets are no longer depreciated once classified as held for sale. These assets are included in the prepaid expenses and other account and classified as
current assets on the consolidated balance sheet. As of August 31, 2010, there were no assets classified as held for sale. The following table sets forth the components of assets held for sale:



|                                            |  |                |       |

During the fiscal years ended August 31, 2010, 2009 and 2008, the Company identified impairments for certain drive-in
assets and surplus property through regular quarterly reviews of long-lived assets. The recoverability of Company-owned Drive-Ins is assessed by estimating the undiscounted net cash flows expected to be generated over the remaining life of the
Company-owned Drive-Ins. This involves estimating same-store sales and margins for the cash flows period. When impairment exists, the carrying value of the asset is written down to fair value.

3. Assets Held for Sale and Impairment of Long-Lived Assets (continued)



During fiscal year 2010, the Company experienced lower sales and profits in Company-owned Drive-Ins due
to the sustained economic downturn and weaker results than anticipated during the summer months for operating stores. Accordingly, the Company revised its future sales growth assumptions and estimated cash flows in assessing the recoverability of
its investments in Company-owned Drive-Ins. These analyses resulted in provisions for impairment totaling $15,162, including $11,341 to write down the carrying amount of building and leasehold improvements on underperforming drive-ins and $2,316 to
write down the carrying amount of property leased to franchisees and $616 to reduce to fair value the carrying amount of 12 surplus properties.

During fiscal year 2009, the Companys assessment of long-lived assets resulted in provisions for impairment totaling $11,163, including $7,462 to
write down the carrying amount of building and leasehold improvements on underperforming drive-ins, $3,276 to write down the carrying amount of equipment on underperforming drive-ins and $425 to reduce to fair value the carrying amount of six
surplus properties.

During fiscal year 2008, these analyses resulted in provisions for impairment totaling $571, including $99 to write down
the carrying amount of building and leasehold improvements on an underperforming drive-in, and $472 to reduce to fair value the carrying amount of five surplus properties.

4. Accounts and Notes Receivable

The Companys receivables are primarily due from franchisees, all of whom are in the restaurant business. The notes
receivable from advertising funds represent transactions in the normal course of business. Substantially all of the notes receivable from franchisees are collateralized by real estate or equipment.

5. Goodwill and Other Intangibles

The entire balance of the Companys goodwill relates to Company-owned Drive-Ins. The changes in the carrying amount of goodwill for fiscal years
ending August 31 were as follows:



|                                                                             |  |      |        |   |      |   |         |

5. Goodwill and Other Intangibles (continued)



The gross carrying amount of franchise agreements, franchise fees and other intangibles subject to
amortization was $6,957 and $7,823 at August 31, 2010 and 2009, respectively. The estimated amortization expense for each of the five years after August 31, 2010 is approximately $325. Accumulated amortization related to these intangible
assets was $2,248 and $1,856 at August 31, 2010 and 2009, respectively.

6. Refranchising of Company-owned Drive-Ins

During fiscal year 2009, the Company refranchised the operations of 205 Company-owned Drive-Ins and recorded a $13.2 million gain. We
retained a noncontrolling operating interest in 88 of these refranchised drive-ins. In fiscal year 2010, the Company refranchised the operations of 16 Company-owned Drive-Ins. Gains and losses are recorded as other operating income (expenses), net
on the Consolidated Income Statement. The Company has concluded its refranchising plan but may periodically refranchise other operations when conditions warrant.

7. Leases

Description of Leasing Arrangements

The Companys leasing operations consist principally of leasing certain land, buildings and equipment (including signs) and subleasing certain
buildings to franchise operators. The land and building portions of these leases are classified as operating leases and expire over the next 18 years. The equipment portions of these leases are classified principally as direct financing leases and
expire principally over the next 10 years. These leases include provisions for contingent rentals that may be received on the basis of a percentage of sales in excess of stipulated amounts. Income is not recognized on contingent rentals until sales
exceed the stipulated amounts. Some leases contain escalation clauses over the lives of the leases. Most of the leases contain one to four renewal options at the end of the initial term for periods of five years.

In fiscal year 2009, as a component of the refranchising of Company-owned Drive-Ins, the Company executed two significant master lease agreements with
franchisees. These leases consist of leasing land, building and signs for a period of 15 years and are classified as operating leases. There are four renewal options at the end of the primary term for periods of five years for property
that is owned by the Company. For property owned by third parties, the lease term runs concurrent with the term of the third party lease arrangements. These leases include provisions for contingent rentals that may be received on the basis of a
percentage of sales in excess of stipulated amounts. Both leases contain escalation clauses based on sales over the life of the lease.

Certain
Company-owned Drive-Ins lease land and buildings from third parties. These leases, which expire over the next 17 years, include provisions for contingent rents that may be paid on the basis of a percentage of sales in excess of stipulated amounts.
For the majority of leases, the land portions are classified as operating leases and the building portions are classified as capital leases.

Direct Financing Leases

|Unredeemed gift cards and gift certificates       |  |      | 8,586  |  |      |   | 7,109  | 
|Other                                             |  |      | 9,663  |  |      |   | 8,417  | 
|                                                  |  |      |        |  |      |   |        |

The Company sells gift cards that do not have expiration dates. The gift card balances are recorded as a liability on the
balance sheet. Breakage is the amount on a gift card that is not expected to be redeemed and that the Company is not required to remit to a state under unclaimed property laws. The Company estimates breakage based upon the trend in redemption
patterns from previously sold gift cards utilizing our history with the program. The Companys policy is to recognize quarterly the breakage on the delayed recognition method when it is apparent that there is a remote likelihood the gift card
balance will be redeemed based on our historical trends. The Company reduces the gift card liability for the estimated breakage and uses that amount to help defray the costs of operating the gift card program.

10. Long-Term Debt

Long-term debt
consists of the following at August 31:



|                                               |  |      |         |  |      |   |         |

|                                               |  |      |         |  |      |   |         | 
|                                               |  |      | 591,621 |  |      |   | 699,550 | 
|Less long-term debt due within one year        |  |      | 61,749  |  |      |   | 52,699  | 
|                                               |  |      |         |  |      |   |         |

|                                               |  |      |         |  |      |   |         | 

Maturities of long-term debt as of August 31, 2010 are $61,749 in 2011, $78,585 in 2012, $450,949 in 2013 and $226 in
2014.

In December 2006, various subsidiaries of the Company issued $600,000 of Class A-2 senior notes in a private transaction. The
Class A-2 senior notes are the first issuance under a facility that will allow Sonic to issue additional series of notes in the future subject to certain conditions. These notes have a fixed interest rate of 5.7%, subject to upward adjustment
after the expected six-year repayment term. Loan origination costs associated with this debt totaled $20,564, and the unamortized balance is categorized as debt origination costs, net, on the Consolidated Balance Sheet as of August 31, 2010.
Amortization of these loan costs and the hedge loss discussed below produces an overall weighted average interest cost of 6.7%.

10. Long-Term Debt (continued)



In connection with issuance of the Class A-2 notes, various subsidiaries of the Company also
completed a securitized financing facility of Class A-1 senior variable funding notes. This facility allows for the issuance of up to $200,000 of notes and certain other credit instruments, including letters of credit. Considering the $187,250
outstanding at August 31, 2010 and $325 in outstanding letters of credit, $12,425 was unused and available under the Class A-1 notes. The effective interest rate on the outstanding balance for the Class A-1 notes at August 31,
2010 and 2009 was 1.41% and 1.42%, respectively. There is a commitment fee on the unused portion of the Class A-1 notes of 0.5%. During fiscal year 2009, upon request of the Company to draw down the remaining $12,250 in Class A-1 senior
variable funding notes from the lender that committed to advance one-half of the funds for the variable funding notes, the lender, which had previously filed for Chapter 11 bankruptcy, notified the Company that it could not meet its obligation. At
this time, the Company no longer considers the $12,250, to be available.

The Class A-1 and Class A-2 notes were issued by special
purpose, bankruptcy remote, indirect subsidiaries of the Company that hold substantially all of Sonics franchising assets and Company-owned Drive-In real estate used in operation of the Companys existing business. As of August 31,
2010, total assets for these combined indirect subsidiaries were approximately $420,000, including receivables for royalties, Company-owned Drive-In real estate, intangible assets, loan origination costs and restricted cash balances of $22,231. The
Notes are secured by Sonics franchise royalty payments, certain lease and other payments and fees and, as a result, the repayment of these notes is expected to be made solely from the income derived from these indirect subsidiaries
assets. Sonic Industries LLC, which is the subsidiary that acts as franchisor, has guaranteed the obligations of the co-issuers and pledged substantially all of its assets to secure such obligations.

While the Class A-1 and A-2 notes have a legal final maturity date of December 2031, the notes are structured to provide for a six-year life with
full repayment expected to occur by December 20, 2012. The Company expects to refinance the notes on or before December 20, 2012. However, if the debt extends beyond December 20, 2012, the terms of the notes provide for a 1%
increase in the interest rate for the Class A-1 notes and an increase in the interest rate for the A-2 notes based on current market conditions. In addition, principal payments will accelerate by applying all of the residual from the royalties,
lease revenues and other fees securing the debt, after the required debt service payments, until the debt is paid in full.

On March 24,
2010, the Office of the Commissioner of Insurance of the State of Wisconsin (OCI) commenced rehabilitation proceedings with respect to a segregated account of certain insurance policies held by Ambac Assurance Corporation
(Ambac), the third-party insurance company that provides credit enhancements in the form of financial guaranties of our fixed and variable rate note payments (the Segregated Account). Our insurance policy is not included in
the Segregated Account and is not affected by the rehabilitation proceedings. Apart from its actions with regard to the Segregated Account, the OCI continues to maintain oversight of Ambac. No delinquency, rehabilitation or similar proceeding
involving our insurance policy is currently pending. If the insurance company were to become the subject of insolvency or similar proceedings, our lenders would not be required to fund additional advances on our variable rate notes. In addition, an
event of default would occur if: (i) the insurance company were to become the subject of insolvency or similar proceedings and (ii) the insurance policy were not continued or sold to a third party (who would assume the insurance
companys obligations under the policy), but instead were terminated or canceled as a result of those proceedings. In an event of default, all unpaid amounts under the fixed and variable rate notes could become immediately due and payable only
at the direction or consent of holders with a majority of the outstanding principal. Such acceleration of our debt repayment could have a material adverse effect on our liquidity if we were unable to negotiate mutually acceptable new terms with our
lenders or if alternate funding were not available to us. While no assurance can be provided, if acceleration of our debt repayment were to occur, we believe that we could negotiate mutually acceptable terms with our lenders or obtain alternate
funding.

We pay Ambac for the financial guarantees of our Class A-1 and Class A-2 note payments in the form of a fixed percentage
applied to the outstanding principal balance of the guaranteed debt. The financial guarantees are unconditional and irrevocable guarantees that note holders will receive timely payment of principal and interest. The insurance fee, which is included
in the interest rate on the debt, is accrued monthly and included in interest expense in the Consolidated Statements of Income.

10. Long-Term Debt (continued)



Although Sonic Corp. does not guarantee the Class A-1 and Class A-2 notes, Sonic Corp. has
agreed to cause the performance of certain obligations of its subsidiaries, principally related to the servicing of the assets included as collateral for the notes and certain indemnity obligations.

In August 2006, the Company entered into a forward starting swap agreement with a financial institution to hedge part of the exposure to changing
interest rates until the new financing was closed in December 2006. The forward starting swap was designated as a cash flow hedge, and was subsequently settled in conjunction with the closing of the Class A-2 notes, as planned. The loss
resulting from settlement of $5,640 ($3,483, net of tax) was recorded in accumulated other comprehensive income and is being amortized to interest expense over the expected term of the Class A-2 notes. Amortization of this loss during fiscal
years 2010 and 2009 totaled $1,064 ($657, net of tax) and $1,050 ($691, net of tax) in interest expense, respectively. Over the next 12 months, the Company expects to amortize $676 ($418, net of tax) to interest expense for this loss. The cash flows
resulting from these hedge transactions are included in cash flows from operating activities on the Consolidated Statement of Cash Flows.

During the third quarter of fiscal 2010, the Company purchased $57,993 of its 5.7% fixed rate notes at a discount. The net loss, after the write-off of
associated debt costs, was $314 and is included as a loss from early extinguishment of debt in net interest expense. During the second quarter of fiscal 2009, the Company purchased $24,985 of its 5.7% fixed rate notes at a discount. The net gain,
after the write-off of associated debt costs, was $6,382 and is included as a gain from early extinguishment of debt, offsetting net interest expense.

The following table presents the components of comprehensive income for the years ended August 31:

Prior to the adoption of Topic 810, noncontrolling interests were reported as a component of operating income. Due to the
adoption, noncontrolling interests are now presented pre-tax as net income-noncontrolling interests and no longer as a component of operating income. This presentation gives an appearance of a lower effective tax rate than the Companys actual
effective tax rate. The following table reconciles the difference in the effective tax rate as a result of adoption of this topic:

State net operating loss carryforwards expire generally beginning in 2011. Management does not believe the Company will be
able to realize the state net operating loss carryforwards and therefore has provided a valuation allowance of $5.5 million and $5.2 million as of August 31, 2010 and August 31, 2009, respectively.

As of August 31, 2010, the
Company had approximately $5,628 of unrecognized tax benefits, including approximately $1,368 of interest and penalty. The liability for unrecognized tax benefits increased by $2,209 in fiscal year 2010. The majority of the change resulted
from an increase to tax positions of prior years due to an uncertain tax position that was challenged under audit. Reductions included positions for prior years in which cash settlements of audits were less than the liability recorded and positions
in which the statute of limitations has expired. The Company recognizes estimated interest and penalties as a component of its income tax expense, net of federal benefit. If recognized, $3,891 of unrecognized tax benefits would favorably impact the
effective tax rate. A reconciliation of the beginning and ending amount of the unrecognized tax benefits follows:

The Company or one of its subsidiaries is subject to U.S. federal income tax and income tax in multiple U.S. state
jurisdictions. The Company is currently undergoing examinations or appeals by various state and federal authorities. The Company anticipates that the finalization of these examinations or appeals, combined with the expiration of applicable
statutes of limitations and the additional accrual of interest related to unrecognized benefits on various return positions taken in years still open for examination could result in a change to the liability for unrecognized tax benefits during the
next 12 months ranging from a decrease of $233 to a decrease of $3,810, depending on the timing and terms of the examination resolutions.

13. Stockholders Equity

Stock
Purchase Plan

The Company has an employee stock purchase plan for all full-time regular employees. Employees are eligible to purchase
shares of common stock each year through a payroll deduction not in excess of the lesser of 10% of compensation or $25 in the stocks fair market value. The aggregate amount of stock that employees may purchase under this plan is limited to
1,139 shares. The purchase price will be between 85% and 100% of the stocks fair market value and will be determined by the Companys Board of Directors.

Stock-Based Compensation

The Sonic Corp. 2006 Long-Term Incentive Plan (the 2006
Plan) provides flexibility to award various forms of equity compensation, such as stock options, stock appreciation rights, performance shares, restricted stock and other stock-based awards. At August 31, 2010, 2,327 shares were available
for grant under the 2006 Plan. The Company has historically granted only stock options with an exercise price equal to the market price of the Companys stock at the date of grant, a contractual term of seven to ten years, and a vesting period
of three years. The Companys policy is to recognize compensation cost for these options on a straight-line basis over the requisite service period for the entire award. Additionally, the Companys policy is to issue new shares of common
stock to satisfy stock option exercises.

In November 2009, the Companys Board of Directors authorized a stock option exchange program
that allowed eligible employees the opportunity to exchange certain options granted under the 2006 Plan, the 2001 Stock Option Plan, and the 1991 Stock Option Plan for a lesser number of replacement options with a lower exercise price. The
Companys stockholders approved the stock option exchange program on January 14, 2010, and the Company executed the program in the third quarter of fiscal year 2010. The exchange, which was accounted for as a modification of existing stock
options, was on an estimated fair value neutral basis and resulted in no incremental compensation expense. The exchange resulted in a tax benefit of $1.8 million for the conversion of eligible incentive stock options to nonqualified stock options.
This tax benefit was recognized during the third quarter of fiscal 2010.

13. Stockholders Equity (continued)





In January 2009, the Company began
to award restricted stock units (RSUs) to its directors under the 2006 Plan. In addition, in fiscal 2010, the Company awarded RSUs to certain officers under the 2006 Plan. The RSUs have a vesting period of three years, their fair
value is based on our closing stock price on the date of grant, and they are payable in the Companys common stock.

In 2009, the Company
awarded 426 performance share units (PSUs) to certain executives under the 2006 Plan. These PSUs, which vested at the end of a three-year period if certain Company performance criteria were met, were payable in the Companys common
stock. As of August 31, 2009, there were 413 PSUs outstanding which had a weighted-average grant date fair value of $10.15 and a total fair value of $4,192. All outstanding PSUs were canceled in August 2010 due to the performance criteria for
the first two years not being met and having no probability of performance in the future. No expense had been recorded for these PSUs.

The
Company measures the compensation cost associated with stock-based payments by estimating the fair value of stock options as of the grant date using the Black-Scholes option pricing model. The Company believes that the valuation technique and the
approach utilized to develop the underlying assumptions are appropriate in calculating the fair values of the Companys stock options granted during 2010, 2009 and 2008. Estimates of fair value are not intended to predict actual future events
or the value ultimately realized by the employees who receive equity awards.

The per share weighted average fair value of stock options
granted during 2010, 2009 and 2008 was $3.40, $3.50 and $6.10, respectively. In addition to the exercise and grant date prices of the awards, certain weighted average assumptions that were used to estimate the fair value of stock option grants in
the respective periods are listed in the table below:



|                        |  |      |     |   |      |  |     |      |  |  |     |

|                        |  | 2010 |     |   | 2009 |  |     | 2008 | 
|Expected term (years)   |  |      | 4.5 |   |      |  | 4.6 |      |  |  | 4.5 |  
|Expected volatility     |  |      | 45  | % |      |  | 38  | %    |  |  | 28  | %
|Risk-free interest rate |  |      | 2.2 | % |      |  | 1.4 | %    |  |  | 3.1 | %
|Expected dividend yield |  |      | 0   | % |      |  | 0   | %    |  |  | 0   | %

The Company estimates expected volatility
based on historical daily price changes of the Companys common stock for a period equal to the current expected term of the options. The risk-free interest rate is based on the United States treasury yields in effect at the time of grant
corresponding with the expected term of the options. The expected option term is the number of years the Company estimates that options will be outstanding prior to exercise considering vesting schedules and our historical exercise patterns.

Cash flows resulting from the tax benefits for tax deductions in excess of the compensation expense recorded for those options (excess tax
benefits) are required to be classified as financing cash flows. These excess tax benefits were $146, $776 and $2,033 for the years ended August 31, 2010, 2009 and 2008, respectively, and are classified as a financing cash inflow in the
Companys Consolidated Statements of Cash Flows. The proceeds from exercises of stock options are also classified as cash flows from financing activities and totaled $3,404, $3,794 and $5,796 for each of the years ended August 31, 2010,
2009 and 2008, respectively.

Restricted Stock Units

The fair value
of each RSU granted is equal to the market price of the Companys stock at the date of the grant. A summary of the Companys RSU activity during the year ended August 31, 2010 is presented in the following table:

Accumulated Other Comprehensive Income

In August 2006, the Company entered into a forward starting swap agreement with a financial institution to hedge part of the interest rate risk associated with the pending securitized debt transaction.
The forward starting swap was designated as a cash flow hedge, and was subsequently settled in conjunction with the closing of the Class A-2 notes, as planned. The loss resulting from settlement was recorded net of tax in accumulated other
comprehensive income and is being amortized to interest expense over the expected term of the debt. See Note 10 for additional information.

14. Segment Information

ASC Topic 280 establishes annual and interim reporting standards for an enterprises operating segments. Operating segments are
generally defined as components of an enterprise about which separate discrete financial information is available as the basis for management to allocate resources and assess performance.

Based on internal reporting and management structure, the Company has determined that it has two reportable segments: Company-owned Drive-Ins and Franchise Operations. The Company-owned Drive-Ins segment
consists of the drive-in operations in which the Company owns a controlling ownership interest and derives its revenues from operating drive-in restaurants. The Franchise Operations segment consists of franchising activities and derives its revenues
from royalties and initial franchise fees received from franchisees. The accounting policies of the segments are described in the Summary of Significant Accounting Policies. Segment information for total assets and capital expenditures is not
presented as such information is not used in measuring segment performance or allocating resources between segments.

The following table
presents the revenues and income from operations for each reportable segment, along with reconciliation to reported revenue and income from operations:

The Company has a Net Revenue Incentive Plan (the Incentive Plan), as amended, which applies to certain members of management and is at all times discretionary with the Companys Board of
Directors. If certain predetermined earnings goals are met, the Incentive Plan provides that a predetermined percentage of the employees salary may be paid in the form of a bonus. The Company recognized as expense incentive bonuses of $828,
$1,187, and $1,324 during fiscal years 2010, 2009 and 2008, respectively.

17. Contingencies

The Company is involved in various legal proceedings and has certain unresolved claims pending. Based on the information currently
available, management believes that all claims currently pending are either covered by insurance or would not have a material adverse effect on the Companys business or financial condition.

The Company initiated an agreement with First Franchise Capital Corporation (FFCC) in September 2006, pursuant to which existing Sonic
franchisees may qualify with FFCC to finance drive-in retrofit projects. The agreement provides that Sonic will guarantee at least $250 of such financing, limited to 5% of the aggregate amount of loans, not to exceed $3,750. As of August 31,
2010, the total amount guaranteed under the FFCC agreement was $563. The agreement provides for release of Sonics guarantee on individual loans under the program that meet certain payment history criteria at the mid-point of each loans
term. Existing loans under the program have terms through 2016. In the event of default by a franchisee, the Company is obligated to pay FFCC the outstanding balances, plus limited interest and charges up to Sonics guarantee limitation. FFCC
is obligated to pursue collections as if Sonics guarantee were not in place, therefore, providing recourse with the franchisee under the notes. The Company is not aware of any defaults under this program. The Companys liability for this
guarantee, which is based on fair value, is $215 as of August 31, 2010.

The Company has an agreement with GE Capital Franchise Finance
Corporation (GEC), pursuant to which GEC made loans to existing Sonic franchisees who met certain underwriting criteria set by GEC. Under the terms of the agreement with GEC, the Company provided a guarantee of 10% of the outstanding
balance of loans from GEC to the Sonic franchisees, limited to a maximum amount of $5,000. As of August 31, 2010, the total amount guaranteed under the GEC agreement was $946. The Company ceased guaranteeing new loans under the program during
fiscal year 2002 and has not recorded a liability for the guarantees under the program. Existing loans under guarantee will expire through 2013. In the event of default by a franchisee, the Company has the option to fulfill the franchisees
obligations under the note or to become the note holder, which would provide an avenue of recourse with the franchisee under the notes. One franchisee participating in the GEC financing program entered into bankruptcy, and the Company fulfilled its
obligation under the program by paying the guaranteed amount of $166 during the third quarter of fiscal 2010.

The Company has obligations
under various lease agreements with third-party lessors related to the real estate for Company-owned Drive-Ins that were sold to franchisees. Under these agreements, the Company remains secondarily liable for the lease payments for which it was
responsible as the original lessee. As of August 31, 2010, the amount remaining under guaranteed lease obligations for which no liability has been provided totaled $10,489. In addition, capital lease obligations totaling $1,070 are still
reflected as liabilities as of August 31, 2010 for properties sold to franchisees. At this time, the Company has no reason to anticipate any default under the foregoing leases.

19. Fair Values of Financial
Instruments

The following discussion of fair values is not indicative of the overall fair value of the Companys consolidated balance
sheet since ASC Topic 825 does not apply to all assets, including intangibles.

The following methods and assumptions were used by the Company
in estimating its fair values of financial instruments:

Cash and cash equivalentsCarrying value approximates fair
value due to the short duration to maturity.

Notes receivableFor variable rate loans with no significant change
in credit risk since the loan origination, fair values approximate carrying amounts. Fair values for fixed-rate loans are estimated using discounted cash flow analysis, using interest rates that would currently be offered for loans with similar
terms to borrowers of similar credit quality and/or the same remaining maturities.

As of August 31, 2010 and 2009,
carrying values approximate their estimated fair values.

Borrowed fundsFair values for fixed rate borrowings are
estimated using a discounted cash flow analysis that applies interest rates currently being offered on borrowings as similar as available in terms of amounts and terms to those currently outstanding. There are few leveraged loan transactions
occurring in the current market. Market information available for public debt transactions for companies with ratings that are close to or lower than ratings for the Company (without consideration for the third-party credit enhancement) was used in
estimating fair value. Management believes this fair value is a reasonable estimate with the information that is available.

The carrying amounts, including accrued interest, and estimated fair values of the Companys fixed-rate borrowings at August 31,
2010 were $404,028 and $388,095, respectively, and at August 31, 2009 were $511,903 and $473,266, respectively. Carrying values, including accrued interest, and estimated fair values for variable-rate borrowings at August 31, 2010 were
$187,327 and $163,552, respectively, and at August 31, 2009 were $187,333 and $159,303, respectively.
